Two zinc and cadmium coordination polymers constructed with bis(4-(1H-imidazol-1-yl)phenyl)methanone and naphthalene-1,4-dicarboxylate ligands: synthesis and structural characterization

Two coordination polymers, [Zn 2 (bipmo) 2 (1,4-nda) 2 ] n ( 1 ), {[Cd(bipmo)(1,4-nda)]·(H 2 O)} n ( 2 ), (bipmo = bis(4-(1 H -imidazol-1-yl)phenyl)methanone, H 2 (1,4-nda) = naphthalene-1,4-dicarboxylic acid), were synthesized under solvothermal conditions. The complexes have been characterized by elemental analyses, IR spectroscopy and single-crystal X-ray diffraction. Complex 1 possesses 3D 2-fold interpenetrating nets with the Schläfli symbol {6 5 ·8}. Complex 2 consists a 3D net with the Schläfli symbol {4 4 ·6 10 ·8}. The luminescent properties of complexes 1 and 2 have been investigated.
