The title compound, [Cu2Cl4(C5H5NO)2]n, is a one-dimensional polymer in which the CuII atoms are alternately bridged by two O atoms [CuCu = 3.2131 (10) Å] and two Cl atoms [CuCu = 3.7061 (11) Å]. The metal centers display a very distorted coordination geometry, with the four stronger bonds defining a CuCl2O2 polyhedron midway between square planar and tetrahedral, which serves as the base of a pyramid, while the loosely bound Cl atom in the bridge occupies the apex. The simultaneous presence of a good hydrogen-bond acceptor and an adequate C-H donor leads to a network of C–HCl interactions.
