“…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.…”

“…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 ...

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.

Source of materialAm ixture of 5-sulfoisophthalic acid monosodium salt (SIP, 0.027 g, 0.1 mmol), Co(CH 3 COO) 2 (0.018 g, 0.1 mmol), 2,2'-bipyridine (2,2'-bipy, 0.016 g, 0.1 mmol) and H 2O( 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 Hatoms were located in difference Fourier maps and refined as riding in their as-found relative positions with U iso(H) = 1.2 U eq (O). The high R value is caused by the low quality of the crystal. DiscussionThe rational design and synthesis of metal-directed supramolecular framework is of great current interest due to their potential application in the catalysis, gas absorption, nonlinear optics, ionexchange, and so on [1-4]. 5-Sulfoisophthalic acid (SIP), containing two kinds of coordinating functional groups and multiple coordination sites, is ag ood ligand for the construction of metalorganic frameworks [5][6][7][8][9][10][11][12]. The title compound possesses acrystal structure constructed from Co ions and SIP anions and 2,2'-bipy ligands. The asymmetric unit contains two Co(II) atoms. Each Co center has distorted octahedral coordination. The coordination of Co1 is defined by two nitrogen atoms of the 2,2'-bipy ligand, one carboxylate oxygen donor and one bridging aqua ligand at the equatorial positions. The axial positions are occupied by one terminal water molecule and one bridging water molecule. The Co2 center is located on the twofold rotation axis and coordinated by two nitrogen atoms from 2,2'-bipy ligand and four terminal water molecules. Two nitrogen atoms and two terminal water molecules form the equatorial plane and the remaining coordinated water molecules occupy the axial positions. The Co-Ob ond lengths are in the range of 2.058 (4) 2+ cations serve for the charge balance. The complex cations and anions align in alternating mode, which is made possible by the well-matched ionic size, and interact with each other via hydrogen bonds between the sulfonate groups and the coordinated water molecules, resulting in the formation of infinite Z.
