Resumo[Cu(tmtp)Br]n (tmtp = tri-m-tolylphosphine) reacts with heterocyclic thiones (L) [L = pyridine-2-thione (py2SH), 1,3-thiazolidine-2-thione (tzdtH), benz-1,3-imidazoline-2-thione (bzimtH2), benz-1,3-thiazoline-2-thione (bztzdtH), imidazoline-2-thione (imtH), benz-1,3-oxazoline-2-thione (bzoxtH2), 5-nitrobenz-1,3-imidazoline-2-thione (nbzimtH2), and 5-methyl-benz-1,3-imidazoline-2-thione (mebzimtH2)] to give binuclear complexes of the general formula [Cu(tmtp)(L)Br]2. These complexes have been characterized by various spectroscopic methods. The crystal structure of the pyridine-2-thione complex has been determined by single-crystal X-ray diffraction methods. The molecule contains a planar Cu2S2 moiety with CuS bond lengths of 2.3348(9) and 2.4879(7) Å. The CuBr and CuP distances are 2.4929(1) and 2.2525(4) Å, respectively, whereas the Cu⋯Cu separation is 2.6906(1) Å.
