Abstract: Three novel polymers, {[Cd(m-bdc)(L)]·H2O} n (1), [Co(m-bdc)(L)0.5(H2O)] n (2) and [Zn5(L)2(p-bdc)5(H2O)] n (3) based on 1,1′-bis(pyridin-3-ylmethyl)-2,2′-biimidazole (L) ligand and benzenedicarboxylate isomers, have been prepared and structurally characterized. Compound 1 exhibits a 2D architecture with (42·6)(42·67·8) topology, which is synthesized by L and 1,3-benzenedicarboxylate (m-bdc) ligands. Compound 2 is constructed from 1D chains that are linked by L ligands extending a 2D (4,4) grid. Compound 3 is a 3D framework with (43)(46·618·84) topology, which is composed of trinuclear clusters and five-coordinated metal centers joined through 1,4-benzenedicarboxylate (p-bdc) and L ligands. Moreover, the fluorescent properties of L ligand, compounds 1 and 3 are also determined. [Copyright &y& Elsevier]
