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 CuI 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.
