“…1,2,4,5-benzenetetracarboxylic acid has got much more attention in the recent years due to its strong coordination capabilityand variouscoordination modes, such as non-coordinate [1], monodentate [2], m 2 -bridging [1,3], m 3 -bridging [4], m 4 -bridging [5], m 5-bridging [6], m6-bridging [7], m2 and m4 together [8] as well as m 4 and m6 together [9]. The structuredescribed here is an isotype to the previously published zinc [10], manganese and nickel analogues [11].…”

Source of material 1,2,4,5-benzenetetracarboxylic acid( 0.508 g, 2m mol; 1,2,4,5-BTC) and NaOH (0.16 g, 4mmol) were dissolved in 15 ml water. Asolution of Cu(NO 3)2 ·3H2O(0.242 g, 1mmol) in 10 ml methanol was added, and the resulting mixture was stirred at 333Kfor 4h ,t hen cooled to room temperature.S ome weeksl ater, blue block-shapedcrystals were grownfrom the filtrate by slow evaporation. The crystal structure consists of the heteronuclear copper and sodium complex containing 1,2,4,5-benzenetetracarboxylic acid being partly deprotonated and m2-bridging. All Cu II and Na I atoms are situated on special positions and are six-coordinated in distorted octahedral environments. The Na I is coordinated by two carboxyl Oatoms from two 1,2,4,5-BTC ligands (d(Na-O4) = 2.276(1) Å)and four Oatoms of four bridging water molecules (d(Na-O)=2.458(2) Å,2.459(2) Å,2.494(2) Å and 2.596(2) Å). The Cu II is coordinated by six watermolecules in which four are bridging( d (Cu-O7) =2 .030(2) Å, d(Cu-O6) =2 .301(2) Å) two are non-bridging (d(Cu-O8) =1 .973(2) Å). The bridging water molecules regularly link one Cu II and two Na I atoms so that ao ne-dimensional linear chain structure is generated. The distancesofadjacent Cu···Naand Na···Na pairs are 3.652(2) Å and 3.888(3) Å,respectively. The intra-and intermolecular hydrogen bonds consolidate the chain structure and join it into three-dimensional network. The hydrogen bond O···O lengths are in the range of 2.392(2) Å to 2.865(2) Å.

“…Macrocyclic complexes with aromatic and aliphatic polycarboxylate ligands have been proved to be good building blocks for the construction of coordination polymers and multi-dimensional supramolecular networks [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. For example, the reaction of [Ni(L)]Cl 2 Á 2H 2 O with 1,3,5-benzenetricarboxylic acid (H 3 btc) yields 2D nickel(II) complex via covalent and hydrogen bonds {[Ni(L)] 3 [l-btc] 2 Á 8H 2 O} n [12], which reveals a geometrically symmetric core with a {4/6}coordination number set.…”

“…In both complexes, the different molecular topologies may be due to the flexibility of cyclam compared with the macrocycle L. On the other hand, the copper(II) complex [Cu(L)(l-tp)] n Á 2H 2 O [15] shows that the copper(II) ions in the complex are bridged by the terephthalato anions to form infinite linear chains, where each chain is linked by interchain hydrogen bonding interactions mediated through water molecules. In a fumarate-bridged 1D copper(II) coordination polymer {[Cu(L)(fumarato)] Á 6H 2 O} n [16], the coordination environment around the copper(II) ion shows a Jahn-Teller distorted octahedron in the chain direction. Furthermore, the reaction of CuCl 2 Á 2H 2 O with L and H 2 pdc (2,3-pyrazinedicarboxylic acid) gives rise to a 3D copper(II) complex linked by covalent and hydrogen bonds {[Cu 2 (L)(pdc) 2 (H 2 O) 2 ] Á 12H 2 O} n [19], in which each copper atom reveals an axially elongated octahedral geometry.…”

The reaction of [M(L)]Cl 2 Á 2H 2 O (M = Ni 2+ and Cu 2+ , L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo[14,4, 0 1.18 ,0 7.12 ]docosane) with 1,1-cyclobutanedicarboxylic acid (H 2 -cbdc) generates 1D and 2D hydrogen-bonded infinite chains [Ni(L)(H-cbdc -) 2 ] (1) and [Cu(L)(H-cbdc -) 2 ] (2).(H-cbdc -= cyclobutane-1-carboxylic acid-1-carboxylate). These complexes have been characterized by X-ray crystallography, spectroscopy, and cyclic voltammetry. The crystal structure of 1 shows a distorted octahedral coordination geometry around the nickel(II) ion, with four secondary amines and two oxygen atoms of the H-cbdc -ligand at the trans position. In 2, the coordination environment around the central copper(II) ion shows a Jahn-Teller distorted octahedron with four Cu-N bonds and two long Cu-O distances. The cyclic voltammogram of the complexes undergoes two oneelectron waves corresponding to M II /M III and M II /M I processes. The electronic spectra and electrochemical behavior of the complexes are significantly affected by the nature of the axial H-cbdc -ligand.

“…The effective and facile approach for the synthesis of such complexes is still the appropriate choice. It is well known carboxylate ligands play an important role in coodination chemistry [1,2]. On the other hand, N-containing auxiliary ligands may tune the structures of the resultant metalorganic complexes [3][4][5][6].…”

Source of material 1-hydrogen-2-ethyl-4,5-imidazole dicarboxylate acid (0.019 g, 0.1 mmol), Co(CH 3 CH 2 COO) ⋅ 4H 2 O(0.025 g, 0.1 mmol), and NaOH (0.004 g, 0.1 mmol) were added to water (10 ml) in aTeflon-lined stainless-steel reactor. The mixture was heated at 403 K for 4d,and then slowly cooled down to room temperature. Pink block-shaped crystals of the title compound were obtained. DiscussionThe design and construction of metal-organic coodination polymers is of current interest in the field of supramocular chemistry and crystal engineering. The effective and facile approach for the synthesis of such complexes is still the appropriate choice. It is well known carboxylate ligands play an important role in coodination chemistry [1,2]. On the other hand, N-containing auxiliary ligands may tune the structures of the resultant metalorganic complexes [3][4][5][6]. The asymmetric unit of the title crystal structure consists of a1H-hydrogen-2-ethyl-4,5-imidazoledicarboxylate, aCo(II) ion and a 1,3-di(4-pyridyl)-propane. Co ion is six-coordinated by two carboxlate oxygen atoms and two Natoms of two 1H-2-ethyl-4,5-imidazoledicarboxylate and two Na toms of two 1,3-di(4-pyridyl)propane, forming ad istorted octahedron with.128(2) Å.Furthermore, CoN 4O2 octahedra are bridged by two symmetry-related bipyridyl molecules and two symmetry-related 1H-2-ethyl-4,5-imidazoledicarboxylate molecules forming aone-dimensional chain.
