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

摘要

A new manganese(II) co-ordination polymer, [Mn(bimb)(3)][ClO4](2). 2H(2)O [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. [References: 24]
