The influence of heterocyclic compounds on the formation of coordination polymers in the system of cadmium(II) nitrate tetrahydrate and biphenyl-4,4′-dicarboxylic acid is demonstrated. Two new coordination polymers [Cd(H2O)(bpdc)(im)2] (1, bpdc2– is biphenyl-4,4′-dicarboxylate, im is imidazole) and [(CH3)2NH2]4[Cd6(dmf)(bpdc)8]·10DMF (2) were obtained under solvothermal conditions in the presence of imidazole or benzimidazole, respectively. Product 1 has a chain structure, while compound 2 possesses a three-dimensional structure with the hex topology. The obtained compounds were characterized by IR spectroscopy, thermogravimetry, elemental analysis, and powder X-ray diffraction.
