Synthesis and crystal structure of an infinite one-dimensional chain containing a poly-metallocage of MnII with 4,4′-bis(imidazol-1-ylmethyl)biphenyl

Abstract

A new manganese(II) co-ordination polymer, [Mn(bimb)₃][ClO₄]₂·2H₂O [bimb = 4,4′-bis(imidazol-1-ylmethyl)biphenyl], was synthesized and characterized by X-ray crystallography, magnetic susceptibility and luminescent measurements. The cation structure of the complex is an infinite one-dimensional chain containing a poly-metallocage. Each Mn^II co-ordinates with six nitrogen atoms of six different bimb ligands with a distorted octahedral environment and each bimb ligand in turn binds to two Mn^II. The perchlorate counter ions and water molecules are incorporated between two adjacent chains through four C–H⋯O hydrogen bonds.
