Chlorobis[N-ethoxycarbonyl-N'-(p-methoxyphenyl)thiourea-kappaS]copper(I).

The title copper(I) complex, [CuCl(C(11)H(14)N(2)O(3)S)(2)], was synthesized by the redox reaction of cupric chloride with the corresponding thiourea derivative as reducing agent. The Cu(I) coordination environment is trigonal planar, involving two S atoms and one Cl atom. The presence of intramolecular hydrogen bonds leads to the formation of a cis conformation and promotes the stability of the complex.
