Two new coordination polymers, namely [Mn(µ3-5-nip)(1-meim)2(H2O)]n
(1) and {[Co(µ-5-nip)(1-meim)3]∙H2O}n
(2) (5-nip: 5-nitroisophthalate,
1-meim: 1-methylimidazole), were hydrothermally synthesized and characterized by
IR spectroscopy, elemental analysis, single crystal diffraction and
simultaneous thermal analysis techniques. The 5-nip ligand exhibited two
different coordination modes in its structures. In 1 and 2, 1D chains were
generated by 5-nip ligands and metal (II) ions. In 1 and 2, 5-nip ligand
coordinated to three Mn(II) and two Co(II) ions as bis(monodentate) bridging
mode and a monodentate and bidentate chelating modes, respectively. For 1 and 2, 2D supramolecular layers were formed by hydrogen bonds which
were extend into 3D supramolecular structures via π···π interactions between
two symmetry–related imidazole rings of neighboring molecules. Furthermore,
optical and thermal properties of the complexes were also studied.
