Arsenic(III), antimony(III) and bismuth(III) compounds of the type, [MS2P(OR)(2)}(3)] (where M = As, Sb and Bi; R = o-, m-, p-C6H4Me) were obtained by reactions of MCl3 with ammonium salts of the corresponding O,O'-ditolyl dithiophosphate on refluxing in benzene. These compounds were characterized by elemental analysis, IR, H-1 NMR and P-31 NMR spectroscopy. The single crystal X-ray structures of
[M S2P(OR)(2)}(3)类型的砷(III),锑(III)和铋(III)化合物(其中M = As,Sb和Bi; R = o-,m -,对-C6H4Me)是通过使MCl3与相应的O,O'-二甲苯基二硫代磷酸酯的铵盐在苯中回流反应而获得的。这些化合物通过元素分析,IR,H-1 NMR和P-31 NMR光谱进行表征。确定了三种代表性化合物的单晶X射线结构。[As S2P(OC6H4Me-m)(2)}(3)]中心点0.5C(6)H(14)在空间群P(1)上的晶格上结晶为三斜晶,且a = 10.9396(1),b = 14.1891(2),c = 17.5359(2)埃,alpha = 70.731(1),beta = 84.734(1),伽马= 74.205(1)度,Z = 4,V = 2472.37(5)埃(3) 。[Sb S2P(OC6H4Me-m)(2)}(3)]和[Bi S
