Three different complexes have been synthesized from the reaction of copper(II) halides with the ligand ptc. In the mixed-valence Cu(I)-Cu(II) (2:1) trimer (I), copper(I) and the copper(II) are linked by two asymmetric chlorine bridges and by a bridging ligand, which coordinates the copper(II) with the endo sulfur and the copper(I) with one thione sulfur. The geometry found around Cu(II) represents the first example of a CuCl4S2 octahedron. Crystal structure, electronic spectroscopy, EPR, and magnetic measurements all support a Robin-Day class I classification for this compound. II consists of two polymeric -Cu-Br-Cu-Br-chains held together by the ligand which bridges through all the sulfur atoms and the thione sulfur, which coordinates two copper atoms. Consequently, each ligand is linked to four Cu atoms. Each Cu(I) shows a slightly distorted CuS2Br2 tetrahedral coordination. III is a dimer where Cu(I) is in a tetrahedral geometry involving two terminal ligands via their thione sulfurs and two bridging bromide ions.
