The crystal structure of the title compound has been determined by Patterson and Fourier methods from single-crystal photographic X-ray diffraction data, and refined by full-matrix least-squares methods to R 0.11 (401 reflections). Crystals are orthorhombic, space group Pb21m, a = 9.63(1), b = 10.64(1), c = 6.71(1) Å, Z = 4. The structure comprises a linear chain of copper atoms alternately spaced at 3.32 and 3.39(1) Å, the copper atoms being spanned by ligand and chlorine bridges; the copper environment is basically a distorted tetrahedron: Cu-Cl 2.37 and 2.38(1), Cu-N 1.88 and 1.92(2) Å; N-Cu-NI 128(1), Cl-Cu-ClI, 117(1), N-Cu-Cl, 100-106°.
