Cu(I) Complexes with heterocyclic thiones and triphenylphosphine as ligands. The crystal structure of [Cu(tzdtH)2 (PPh3)2]NO3
1989
Abstract The reactions of bis(triphenylphosphine)copper(I) nitrate with heterocyclic thiones (L) [L = pyridine-2-thione (py2SH), pyridine-4-thione (py4SH), pyrimidine-2-thione (pymtH), 1,3-thiazolidine-2-thione (tzdtH), 1-methyl-1,3-imidazoline-2-thione (meimtH), benz-1,3-imidazoline-2-thione (bzimtH 2 ), benz-1,3-thiazoline-2-thione (bztzH), benz-1,3-oxazoline-2-thione (bzoxtH), 5-nitro-2-benz-l,3-imidazoline-2-thione (nbzimtH 2 ) and quinazolinone-2-thione (qnotH 2 )] lead to the formation of mononuclear complexes of the general formula [Cu(L) 2 (PPh 3 ) 2 ]NO3. The complexes have been characterized by elemental analysis, infrared, UVVis and NMR spectroscopy. The crystal structure of [Cu(tzdtH) 2 (PPh 3 ) 2 ]NO 3 has been determined by single-crystal X-ray diffraction methods. The colorless crystals are monoclinic, space group P 2 1 / c with a = 16.314(2), b = 9.981(2), c = 25.799(3) A, β = 89.39(1)°, V = 4200 A 3 and Z = 4.
