The Synthesis and Crystal Structure of a New 1-D Co (II) Complex Based on Boronic Acid Ligand

Abstract:

The title complex, [Co (ncpb)(μ-4,4'-bpy)(H₂O)₂](4,4'-bpy) (1) (4,4'-bpy = 4,4'-bipyridine, ncpb = 5-nitro-4-carboxylatophenylboronic acid), was synthesized from a hydrothermal reaction of CoCl₂·6H₂O, ncpb ligand and 4,4'-bpy, and characterized by single-crystal X-ray diffraction analysis. The complex 1 crystallizes in monoclinic space group C2/c with a = 27.104(2) Å, b = 11.3566(8) Å, c = 13.5065(10) Å, β = 113.0220(10)°. The structure of 1 is composed of discrete 4,4'-bpy moleculars and 1-D chains originating from terminal ncpb ligands and μ-4,4'-bpy molecules. The chains are further connected through rich intermolecular OH···O and OH···N hydrogen bonds to genenate a 3-D supramolecular architecture.
