A new mixed-ligand one-dimensional copper(II) coordination polymer [Cu(en)(sal)Cl]n where en = ethylenediamine(C2H8N2) and Hsal = 2-hydroxybenzoic acid (salicylic acid; C7H6O3) is synthesized and characterized by FTIR spectroscopy and single crystal X-ray diffraction. The structure contains Cu2+ ions in two different distorted octahedral coordination environments: an axially extended CuN4Cl2 moiety arising from a pair of bidentate en ligands and a CuO4Cl2 moiety arising from a pair of asymmetrically coordinated sal anions. The chloride ions bridge the copper ions into a zigzag chain propagating in [001]. The structure is consolidated by N–H•••O and N–H•••Cl hydrogen bonds which generate a layered network. Crystal data: C9H13ClCuN2O3, Mr = 296.20, monoclinic, P21/c, a = 13.9179(10) Å, b = 10.4900(8) Å, c = 8.5181(6) Å, β = 105.518(4)°, V = 1198.30(15) Å3, Z = 4, R(F) = 0.026, wR(F2) = 0.068.
