摘要
[Cu(PPh3)I]4 reacts with heterocyclic thiones (L) [L = pyrimidine-2-thione (pymtH), 1,3-thiazoline-2-thione (tzdtH), 1,3-imidazoline-2-thione (imtH), benz-1,3-imidazoline-2-thione (bzimtH-2) and benz-1,3-thiazoline-2-thione (bztztH)] in the presence of triphenylphosphine to give mononuclear complexes of the general formula [Cu(PPh3)2 (L)I]. These complexes have been characterized by various physicochemical methods. The crystal structure of [Cu(PPh3)2(pymtH)I] has been determined by single-crystal X-ray diffraction methods. The molecule is mononuclear, with a distorted tetrahedral geometry and bond lengths Cu-S = 2.338(4), Cu-I = 2.674(2), Cu-P = 2.296(4) and 2.303(4) angstrom.
