title: Poly[di-μ(3)-chlorido-[μ(2)-(3-pyrid-yl)(4-pyrid-yl)methanone-κN:N']dicopper(I)].
abstract: In the title compound, [Cu(2)Cl(2)(C(11)H(8)N(2)O)](n), stair-like ribbons of formula [Cu(2)Cl(2)](n) are linked into coordination polymer layers by tethering (3-pyrid-yl)(4-pyrid-yl)methanone (3,4'-dpk) ligands. The two distinct Cu(I) centres both adopt distorted CuNCl(3) tetra-hedral coordinations. Individual [Cu(2)Cl(2)(3,4'-dpk)](n) layers stack in an AB pattern along the c direction by way of weak C-H⋯O inter-actions between the pyridyl rings and ketone O atoms.
