Synthesis and crystal structure of 2D coordination polymer [Mn(HIDC)(H2O)]n constructed by 1H-imidazole-4,5-dicarboxylate ligand

A novel coordination polymer of [Mn(HIDC)(H2O)](n) (HIDC2 = 1H-imidazole-4,5-dicarboxylate dianion) has been synthesized and characterized by elemental analysis, IR spectra and X-ray single crystal diffraction. The title complex crystallizes in orthorhombic with space group Pbca, a = 0.723 00(14) nm, b = 1.361 8(3) nm, c = 1.425 0(3) nm. V = 1.403 0(5) nm(3), Z = 8, R = 0.021 3 and wR=0.059 2. Each manganese(II) atom is six-coordinated by four oxygen atoms and one nitrogen atoms from three different HIDC2- groups and one water molecule, forming a distorted octahedral coordination configuration. The manganese(II) atoms are bridged by the pentadentate HIDC2- groups, constructing a two-dimensional layer structure along ac plane.
