The crystal structures of the title compounds have been established by single-crystal photographic X-ray diffraction methods. Crystals are triclinic, space group P1̄, a = 7.477(4) [7.491 (2)], b = 7.971 (3) [8.069(2)], c = 6.314(3) [6.379(2)] Å, α = 103.18(5) [104.83(2)], β = 93.47(6) [94.11 (2)], γ = 75.45(5) [76.62(2)}]°, Z = 1. The structures were solved by the heavy-atom method and refined by block-diagonal least squares to R0.10 [0.10] for 857 [953] independent reflections. The structure consists of centrosymmetric molecules, the metal atom being planar co-ordinated by four sulphur atoms at 2.217(2) and 2.201(2) [2.342(2) and 2.345(2)] Å. Intraligand distances are normal. There is no evidence in the copper derivative for dimer formation by intermodular metal-sulphur interaction.
