Source of materialThetitle compound was synthesized by adding the CH 3 OH solution (6 mL) of 1,10-phenanthroline (phen, 0.5m mol) and 4-hydroxyphthalic acid (Hpc, 0.5 mmol) dropwise to astirred water solution (4 mL) of Cu(NO 3 ) 2 × 2.5H 2 O(0.5 mmol) at 298 K. Then the reaction mixture was filtered and the filtrate was left standing for about four weeks until the blue block-shaped crystals were obtained.The crystals suitable for X-ray diffraction were collected by filtration, washed with waterand ethanoland driedinair (38% yieldbased on Cu Experimental detailsAll the hydrogen atomswere included in calculated positions and treated as riding with. O9 was refined as split over two sites with the fixed occupancy of 0.5 (d(O9-O9A) =2.686 Å). According to the PLATON check procedure [1],the structure does not contain any additional disordered solvent molecules. DiscussionMetal-organich ybrid materials containing paramagnetic metal ions have attracted intense interest for their fascinating structural diversities and functional applications in the fields of molecular magnetism and material chemistry [2][3][4]. In aspontaneous assembly process, the structural information stored in the organic ligands is read by the metal ion according to their coordination tendency. The choice of appropriate organic ligands and metal is important to construct distinct architectures, from which corresponding properties are derived. The family of benzenedicarboxylate isomers with electron delocalization is prone to transmit magnetic interactions in addition to propagating the network [5][6][7]. In the title crystal structure, the asymmetric unit consists of one Cu 2+ ion, one phen ligand, one deprotonated pc -ligand, one coordinating and 2.5 lattice water molecules. Each Cu(II) ion is fivecoordinated by two nitrogen atomsofone phen ligand and three oxygen atomsf rom two different deprotonated pc -ligands and one coordinating water molecule, forming ad istorted trigonal bipyramid, where N1,N 2a nd O1 locate at thee quatorial positions while O6 and O2Aoccupythe axialpositions.

“…Asuccessful strategy in building such networks is to employ appropriate bridging ligands that can bind metal ions in different modes and provide apossible way to achieve more robust polymeric structures [7,8]. In this context, benzenedicarboxylic acid and its derivatives, such as 1,3-benzenedicarboxylic acid, 1,4-benzenedicarboxylic acid, 5-hydroxyisophthalic acid are widely used as building blocks to link metal ions to produce metal-organic frameworks with interesting structures and properties [9].…”

C 20 H 17 BrN 2 O 5 Zn, triclinic, P1 (no. 2), a =8.036(5) Å, b =9.673(6) Å, c =14.549(9) Å, a =105.706(7)°, b =90.431(7)°, g =114.255(7)°, V =983.5 Å 3 , Z =2, R gt (F) =0.030, wR ref (F 2 ) =0.074, T =294 K. Source of materialThe title compound was synthesized by the reaction of 1,2-bi(4-pyridyl)ethane (bpa, 0.5 mmol), 5-bromoisophthalic acid (0.5 .mmol), Zn(OAc)2.·.4H2O(0.5 mmol) and KOH (0.5 mmol) were added to water (12 ml) in aTeflon-lined stainless steel reactor. The mixture was heated at 400 Kf or 5d ,a nd then slowly cooled down to room temperature. Colourless crystals of the title compound were obtained. DiscussionDesign of the solid state with molecules that encode well defined noncovalent motifs has recently become arapidly growing area of research due to the fascinating molecular and/or supramolecular structural diversity [1,2] and potential applications for catalysis [3,4] and material sciences [5,6]. Asuccessful strategy in building such networks is to employ appropriate bridging ligands that can bind metal ions in different modes and provide apossible way to achieve more robust polymeric structures [7,8]. In this context, benzenedicarboxylic acid and its derivatives, such as 1,3-benzenedicarboxylic acid, 1,4-benzenedicarboxylic acid, 5-hydroxyisophthalic acid are widely used as building blocks to link metal ions to produce metal-organic frameworks with interesting structures and properties [9]. Recently, benzenedicarboxylic acid, providing specific rigid molecules, seized our attention for constructing various coordination polymer. The interesting results inspired us to investigate its analogues, 2-bromo-1,4-benzenedicarboxylic acid, for the following reasons: (a) it has two carboxyl groups which may be completely or partially deprotonated, inducing rich coordination modes and allowing interesting structures with higher dimensions; (b) it can act not only as hydrogen-bond acceptor but also as hydrogen-bond donor, depending upon the numbers of deprotonated carboxyl groups. In the title crystal structure, the asymmetric unit consists of one zinc(II) ion, one bpa molecule, one 5-bromoisophthalate anion, and one coordinated water molecule. The zinc(II) ion has adistorted trigonal-bipyramidal arrangement (ZnO 4N) with four oxygen atoms from three 5-bromoisophthalate anions and one water molecule, and one nitrogen atom from one bpa molecule. The Zn-Nb ond lengths are both 2.029(3) Å and the Zn-Ob ond lengths are in the range of 1.943(2) -2 .823(3) Å,r espectively. The bpa molecule adopts an unidentate coordination mode and the unligated N2 atom acts as the hydrogen-bonding acceptor.The 5-bromoisophthalate anion shows m 3 -bridging coordination mode, which link the zinc(II) ions into 1D ladder-like framework.The 5-bromoisophthalate anion, bpa molecule and water molecule are involved in intramolecular O-H···O, and O-H···Nhydro-gen bonds, which result in a3Dsupramolecular structure.

Source of materialImidazo[4,5-f]1,10-phenanthroline (ip; 0.5 mmol), 2-bromo-1,4-benzenedicarboxylic acid (0.5 mmol), Mn(OAc) 2 ·4 H 2 O( 123 mg, 0.5 mmol) and KOH (0.5 mmol) were added to water (12 ml) in aTeflon-lined stainless steel reactor. The mixture was heated at 400 Kfor 3days, and then slowly cooled down to room temperature. Yellow crystals of the title compound were obtained. Experimental deatailsThe Br atoms are disordered over two sites, viz. Br1 (bonded to atom C20) and Br2 (bonded to atom C16). The site occupancy factors of Br1 and Br2 atoms were independently refined and converged to 0.890(2) and 0.110(2), respectively [1,2]. DiscussionDesigning the solid state materials with molecules that encode welldefined non-covalent motifs has recently become ar apidly growing area of research due to the fascinating molecular and/or supramolecular structural diversity and potential applications for catalysis [3,4] and material sciences [5,6].

The following reasons inspired us to investigate its analogues, 2-bromo-1,4-benzenedicarboxylic acid: (a)ithas two carboxyl groups which may be completely or partially deprotonated, inducing multiple coordination modesa nd allowing interesting structures with higher dimensions;(b)itcan act not only as hydrogen-bond acceptor but also as hydrogen-bond donor, depending upon the numbers of deprotonated carboxyl groups. In the title crystal structure, the asymmetric unit consists of one Mn 2+ cation, one imidazo[4,5-f]1,10-phenanthroline (ip) molecule, one disordered 2-bromo-1,4-benzenedicarboxylic acid ,two water molecules of crystallization. The Mn(II) ion has aslightly distorted octahedral arrangement (MnO 2 N 4 )w ith four nitrogen atoms from two ip molecules and two carboxylate oxygen atoms from two coordinated benzenedicarboxylic acid molecules. The Mn-O bond lengths are both 2.117(3) Å and the Mn-N bond lengths are in the range of 2.261(3) -2 .306(3) Å,r espectively. Noteworthy, within the asymmetric unit, uncoordinated water molecule O6 acts as hydrogen-bond donor, via H1W and H2W, respectively,t oc arboxylate atom O2 at (x+1/2,y−1/2,z)a nd imidazole atomN 3a t( x +1/2,−y+1/2,z+1/2); Simultaneity, O6 also acts as hydrogen-bond acceptor from carboxylate atom O5 at (x+1,y,z),via H5. The mononuclear units are assembled by hydrogen bonds between ip molecules, benzenedi-carboxylic acid molecules, and uncoordinated water molecules O6 to afford a3D supramolecular structure. The bond lengths and angles of the above three hydrogen bonding parametres are in the range of 2.590(4) -2.849(5) Å and 135.0°-179....
