Crystal Structure of a Novel One-dimensional Chain-like Compound, Catena(μ₂-4,4′-Bipyridyl)-bis(Formato-O,O′)-Copper(II)

Abstract

The title compound, [Cu(C₁₀H₈N₂)(HCO₂)₂]_n, in which the asymmetric unit contains one crystallographically independent copper(II) ions, one formate and half of 4, 4′-bipy molecules, has a linear polymeric structure, with the bridging ligand 4, 4′-bipyridine connecting the Cu^II ions. Each ion lies on an inversion center and has a distorted octahedral environment, being coordinated by two bipy ligands and four oxygen atoms from two formate groups. The O1 in the formate group is disordered over two sites with occupancy of 0.55 and 0.45. In the crystal structure, the linear polymeric chains are linked by intermolecular C–H···O hydrogen bonds, resulting in a two-dimensional supramolecular network.
