Let’s learn more about this compound (cas:27231-36-3).
[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-methylbenz-1,3-imidazoline-2-thione (mebzimtH2)] to give binuclear [Cu(tmtp)(L)Br]2. These complexes were characterized by various spectroscopic methods. The crystal structure of the pyridine-2-thione complex was determined by single-crystal x-ray diffraction methods. The mol. contains a planar Cu2S2 moiety with Cu-S bond lengths of 2.3348(9) and 2.4879(7) Å.
