in which the metal atom is pseudo-tetrahedrally coordinated by two phosphorous atoms from triphenylphosphine ligands and by two sulfur atoms from one chelating p -tolyldithiocarboxylate group. Triphenylphosphine sulfide molecules are also present in the crystals of VIb . The complex autoxidative reactions of some dithiocarboxylates in pyridine, which cause a partial transformation of the sulfur atoms

对甲苯基)。通过使它们与
三苯基膦以不同的比例反应,形成了PPh 3 S,可以分离出以下系列的产物:[[(CuS 3 CAr)2(CuS 2 -CAr)2] py 2(II); [CuS 2 CAr] 4(III); [(CuS 2 CAr)4-(PPh 3)2](IV); [CuS 2 CAr(PPh 3)2](V)。在
对甲苯基的情况下,还获得了复合物[CuS 2 CAr(PPh 3)2]·PPh 3 S(VIb)。报告了上述化合物的一些重要的IR和NMR(13 C,31 P)数据。化合物IIIb和VIb的晶体结构通过单晶X射线衍射法确定。IIIb晶体为三斜晶系,空间群P 1,a = 13.879(4),b = 10.324(3),c = 13.479(4)A,α=
