چکیده
The title compound, [CdNa2(C8H4O4)2(C3H7NO)(H2O)2] n or [CdNa2(1,3-bdc)2(DMF)(H2O)2] n , is a new CdII-NaI heterobimetallic coordination polymer. The asymmetric unit consists of one CdII atom, two NaI atoms, two 1,3-bdc ligands, two coordinated water mol-ecules and one coordinated DMF mol-ecule. The CdII atom exhibits a seven-coordinate geometry, while the NaI atoms can be considered to be penta-coordinate. The metal ions and their symmetry-related equivalents are connected via chelating-bridging carboxyl-ate groups of the 1,3-bdc ligands to generate a three-dimensional framework. In the crystal, there are classical O-H⋯O hydrogen bonds involving the coordinated water mol-ecules and the 1,3-bdc carboxyl-ate groups and π-π stacking between the benzene rings of the 1,3-bdc ligands present within the frameworks.

The title coordination polymer, {[Cd(C8H4O4)(C14H14N4)]·C3H7NO} n , was synthesized by solvothermal reaction of metallic cadmium with the semi-rigid neutral ligand 1,4-bis-[(1H-imidazol-1-yl)meth-yl]benzene (bix) and the V-shaped benzene-1,3-di-carb-oxy-lic acid (m-H2bdc). The structure exhibits a pseudo-C-centring which is almost fulfilled by the polymeric metal complex but not by the solvent ...

In the polymeric title complex, {[Mn(C(8)H(4)O(4))(C(7)H(6)N(2))(H(2)O)(2)]·2H(2)O}(n), the Mn(II) cation is coordinated by two benzene-dicarboxyl-ate anions, one benzimidazole ligand and two water mol-ecules in a distorted MnNO(5) octa-hedral geometry. In the crystal, each benzene-dicarboxyl-ate anion bridges adjacent Mn(II) cations through the terminal carboxyl-ate groups, forming a polymeric...
