“…At a ratio of Cd/SIP/dpp = 3:2:6, the 2D polymer 3 is formed. Reducing the corresponding ratio to 3:2:2 results in the 1D compound {[Cd(SIP)(dpp)(H 2 O) 3 ]·0.5Cd(H 2 O) 6 · 5H 2 O} n , [14] indicating that the reaction products are ratiodependent. The preparative reactions were carried out at different temperatures (140°C, 160°C and 180°C) to examine the temperature dependence of their solid structures.…”

Hydrothermal reactions of Cd(NO3)2 and NaH2SIP (5‐sulfoisophthalic acid monosodium salt) at pH = 2 and 7 produce [Cd2(μ2‐OH2)2(HSIP)2(H2O)6] (1) and [Cd5(μ2‐OH)2(μ3‐OH)2(SIP)2(H2O)5]n (2), respectively. A similar hydrothermal reaction in the presence of dpp [1,3‐bis(4‐pyridyl)propane] yields {[Cd3(SIP)2(dpp)6]·4(H2O)}n (3). Single‐crystal X‐ray diffraction reveals that compound 1 has a discrete dinuclear structure with the [Cd2(μ2‐OH2)2] unit. Polymer 2 features an inorganic layer, which has centrosymmetric 12‐ and 24‐membered rings composed of chair‐shaped [Cd4(μ3‐OH)2] units and Cd(μ2‐OH)2(CO2) units, and is interconnected by SIP into a 3D framework. Complex 3 contains a 1D ladder‐like [Cd4(SIP)4]n unit with four cadmium atoms co‐planar, which is interconnected by dpp into a 2D nanosized layered structure. In the solid state, compounds 1 and 3 exhibit blue‐violet photoluminescence with maxima at 436 and 409 nm upon excitation at 342 and 350 nm, respectively. However, compound 2 shows photoluminescence with the maximum at 306 nm upon excitation at 270 nm.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

“…Introduction of asulfonate group into rigid multicarboxlate ligands may result in the formation of unexpected frameworks as the sulfonic group has adifferent shape and properties in terms of its coordination ability compared to the carboxylate group. Since apseudo-honeycomb coordination polymer constructed by copper(II) and the 5-sulfo-isophthalic acid as ligand was firstly reported [6], the studies of this ligand have received considerable attention [7][8][9][10][11][12][13][14][15]. However, the studies of the 2-sulfoterephthalic acid (H 3 STP) are not very common [16][17][18][19].…”

Source of materialAmixture of STP (2-sulfoterephthalic acid, 0.025 g, 0.1 mmol), CuCl 2 (0.013 g, 0.1 mmol), 2,2'-bipy (0.016 g, 0.1 mmol), and H 2 O(10 ml) was stirred for about 30 min. The resulting solution was sealed in aTeflon-lined stainless autoclave and heated to 393 Kfor 3days. The bottle was cooled to ambient temperature spontaneously. Blue block-like single crystals (about 90 %, based on Cu) were recovered by vacuum filtration and drying in air. Elemental analysis -f ound: C, 32.76 %; H, 4.16 %; N, 5.83 %; calulated for C 36H40Cu2N4O22S2:C,32.84 %; H, 4.24 %; N, 5.90 %. Experimental detailsThe C-bound Ha toms were geometrically placed (d(C-H) = 0.93 Å)and refined as riding with U iso(H) =1.2 Ueq(C). The Obound Ha toms were located in difference maps and refined as riding with U iso (H) =1.2U eq (O). DiscussionTerephthalate is an important rigid multicaboxylate ligand for construction of extended coordination solids owing to its high symmetry and coordination ability for abroad range of metal ions [1][2][3][4][5]. Introduction of asulfonate group into rigid multicarboxlate ligands may result in the formation of unexpected frameworks as the sulfonic group has adifferent shape and properties in terms of its coordination ability compared to the carboxylate group. Since apseudo-honeycomb coordination polymer constructed by copper(II) and the 5-sulfo-isophthalic acid as ligand was firstly reported [6], the studies of this ligand have received considerable attention [7][8][9][10][11][12][13][14][15]. However, the studies of the 2-sulfoterephthalic acid (H 3 STP) are not very common [16][17][18][19]. The asymmetric unit in the title structure contains one copper ion, one 2,2'-bipyridine molecule, one deprotonated HSTP 2-anion and four water molecules. The copper center is surrounded with two pyridine Na toms of a2 ,2'-bipyridine molecule, one carboxylate Oa tom, one water molecule, and one sulfonate O atom. One carboxylate Oatom, one coordinated water molecule and two 2,2'-bipyridine Na toms form the basal plane, and the sulfonate Oatom occupies the apical site. The copper coordination is thus the square pyramidal one. The Cu-N and Cu-Obasal bond lengths range from 1.9538(2) -1.993(2) Å,which is consistent with those found in comparable structures [7,14]. The Cu-O sulfonate bond distance is much longer than that of Cu-O carboxylate which is the most frequent with copper sulfonates. The C-O distances are consistent with the location of the Hatoms deduced from difference maps, which indicate that the HSTP ligand carries ac harge of -2f or charge balance. The HSTP 2-anion coordinates to the symmetry-related copper ions through its sulfonate Oatom and carboxylate Oatom. The whole HSTP 2-ligand links metal centres in a m 2 mode to generate a dimeric unit forming short bridges, which define a14-membered ring. As found in the previous complex [16], the dihedral angle between aromatic ring and the plane of the carboxylate group is 78.54°, which is made possible by the well matched ionic size. The terminal COOH group ...

“…Since a pseudo-honeycomb coordination polymer constructed by Cu 2+ ion and the SIP ligand was firstly reported by Shimizu et al [6], the studies of SIP ligand have received considerable attention. A few analogous compounds based on transition metal ions Cu, Zn, Cd and SIP ligands are reported to date [7][8][9][10][11][12][13] 2+ .The asymmetric unit contains two symmetrically independent Zn atoms. The coordination environment of the Zn1 atom consists of an octahedron, with the basal plane defined by two bipyridine Na toms of a2 ,2'-bipy ligand, one carboxylate oxygen and one bridging water molecule.…”

Source of materialAmixture of 5-sulfoisophthalic acid monosodium salt (NaHSIP; 0.027 g, 0.1 mmol), Zn(CH 3 COO) 2 (0.019 g, 0.1 mmol), 2,2'-bipyridine (bipy, 0.016 g0.1 mmol), and H 2 O(10 mL) was stirred for about 30 min. Experimental detailsThe C-bound Ha toms were geometrically placed (d(C-H) = 0.93 Å)and refined as riding with U iso (H) =1.2 U eq (C). The Obound Ha toms were located in difference maps and refined as riding in their as-found relative positions with U iso(H) =1 .2 U eq (O). DiscussionThe chemistry of 1,3,5-benzenetricarboxylic acid (BTC) has been extensively studied as abuilding block for extended coordination solids owing to its high symmetry and coordination preferences for ab road range of metal ions [1][2][3][4][5]. 5-Sulfoisophthalic acid (H 2 SIP), being astructural analogue of BTC, could be expected also to construct metal organic frameworks. 2+ .The asymmetric unit contains two symmetrically independent Zn atoms. The coordination environment of the Zn1 atom consists of an octahedron, with the basal plane defined by two bipyridine Na toms of a2 ,2'-bipy ligand, one carboxylate oxygen and one bridging water molecule. The remaining two sites are occupied by two coordinated water molecules. Zn2 center coordinates to two symmetry related pyridine N atoms of a2 ,2'-bipyridine molecule and four symmetry related oxygen atoms of aqua ligands. Two bipyridine Natoms and two coordinated water molecules form the basal plane, and the remaining coordinated water molecules occupy the axial positions. The Zn-Ndistances range from 2.092(2) Å to 2.161(2) Å,and Zn-Obond distance is in the range of 2.0311(2) -2.267(2) Å, which is consistent with those found in comparable structures [8]. The SIP ligand adopts an O-monodentate mode, which is different from those found in in comparable structures [7][8][9][10]
