Abstract: The title compound, [Cu₂Cl₄(C₅H₅NO)₂]_n, is a one-dimensional polymer in which the Cu^II 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.
