Poly[di-₃-chlorido-[₂-(3-pyridyl)(4-pyridyl)methanone-²N:N']dicopper(I)]

J. L. Hittle and R. L. LaDuca

Abstract: In the title compound, [Cu₂Cl₂(C₁₁H₈N₂O)]_n, stair-like ribbons of formula [Cu₂Cl₂]_n are linked into coordination polymer layers by tethering (3-pyridyl)(4-pyridyl)methanone (3,4'-dpk) ligands. The two distinct Cu^I centres both adopt distorted CuNCl₃ tetrahedral coordinations. Individual [Cu₂Cl₂(3,4'-dpk)]_n layers stack in an AB pattern along the c direction by way of weak C-HO interactions between the pyridyl rings and ketone O atoms.
