Abstract: The asymmetric unit of the title compound, poly[{μ(4)-4-[(carboxylatomethyl)sulfanyl]benzoato}(N,N-dimethylformamide)zinc], [Zn(C(9)H(6)O(4)S)(C(3)H(7)NO)](n), consists of one crystallographically independent Zn(II) cation, one 4-[(carboxylatomethyl)sulfanyl]benzoate (L(2-)) ligand and one coordinated dimethylformamide (DMF) molecule. The zinc ion is coordinated by five O atoms from four separate L(2-) ligands and one DMF molecule, and the ZnO(5) unit displays a distorted square-based-pyramidal geometry. Two Z… Show more

The asymmetric unit of the title Pb-based coordination polymer, [Pb2(C24H16N2O8)(H2O)2]n, consists of one PbII cation, half of a 4,4′-(1,4-phenylene)bis(2,6-dimethylpyridine-3,5-dicarboxylate (L 4−) ligand and one coordinating water molecule. The centers of the benzene ring of the ligand and the four-membered Pb/O/Pb/O ring are located on centers of inversion. The PbII ion is coordinated in form of a distorted polyhedron by seven O atoms from four separate L 4− ligands and by one water O atom. The PbO7 polyhedra share O atoms, forming infinite zigzag [PbO4(H2O)]n chains along [100] that are bridged by L 4− ligands, forming a two-dimensional coordination network parallel to (001). O—H⋯O hydrogen bonds involving the water molecule are observed.

Semirigid organic ligands can adopt different conformations to construct coordination polymers with more diverse structures when compared to those constructed from rigid ligands. A new asymmetric semirigid organic ligand, 4-{2-[(pyridin-3-yl)methyl]-2H-tetrazol-5-yl}pyridine (L), has been prepared and used to synthesize three bimetallic macrocyclic complexes and one coordination polymer, namely, bis(μ-4-{2-[(pyridin-3-yl)methyl]-2H-tetrazol-5-yl}pyridine)bis[dichloridozinc(II)] dichloromethane disolvate, [Zn2Cl4(C12H10N6)2]·2CH2Cl2, (I), the analogous chloroform monosolvate, [Zn2Cl4(C12H10N6)2]·CHCl3, (II), bis(μ-4-{2-[(pyridin-3-yl)methyl]-2H-tetrazol-5-yl}pyridine)bis[diiodidozinc(II)] dichloromethane disolvate, [Zn2I4(C12H10N6)2]·2CH2Cl2, (III), and catena-poly[[[diiodidozinc(II)]-μ-4-{2-[(pyridin-3-yl)methyl]-2H-tetrazol-5-yl}pyridine] chloroform monosolvate], {[ZnI2(C12H10N6)]·CHCl3} n , (IV), by solution reaction with ZnX 2 (X = Cl and I) in a CH2Cl2/CH3OH or CHCl3/CH3OH mixed solvent system at room temperature. Complex (I) is isomorphic with complex (III) and has a bimetallic ring possessing similar coordination environments for both of the ZnII cations. Although complex (II) also contains a bimetallic ring, the two ZnII cations have different coordination environments. Under the influence of the I− anion and guest CHCl3 molecule, complex (IV) displays a significantly different structure with respect to complexes (I)–(III). C—H...Cl and C—H...N hydrogen bonds, and π–π stacking or C—Cl...π interactions exist in complexes (I)–(IV), and these weak interactions play an important role in the three-dimensional structures of (I)–(IV) in the solid state. In addition, the fluorescence properties of L and complexes (I)–(IV) were investigated.
