摘要

In poly[aqua(μ3-benzene-1,4-dicarboxylato-κ5O1,O1′:O1:O4,O4′)[2-(pyridin-3-yl-κN)-1H-benzimidazole]cadmium(II)], [Cd(C8H4O4)(C12H9N3)(H2O)]n, (I), each CdII ion is seven-coordinated by the pyridine N atom from a 2-(pyridin-3-yl)benzimidazole (3-PyBIm) ligand, five O atoms from three benzene-1,4-dicarboxylate (1,4-bdc) ligands and one O atom from a coordinated water molecule. The complex forms an extended two-dimensional carboxylate layer structure, which is further extended into a three-dimensional network by hydrogen-bonding interactions. In catena-poly[[diaquabis[2-(pyridin-3-yl-κN)-1H-benzimidazole]cobalt(II)]-μ2-benzene-1,4-dicarboxylato-κ2O1:O4], [Co(C8H4O4)(C12H9N3)2(H2O)2]n, (II), each CoII ion is six-coordinated by two pyridine N atoms from two 3-PyBIm ligands, two O atoms from two 1,4-bdc ligands and two O atoms from two coordinated water molecules. The complex forms a one-dimensional chain-like coordination polymer and is further assembled by hydrogen-bonding interactions to form a three-dimensional network.
