摘要
[MOCl4](-) complexes (M = Re, Tc) react with thianes derived from N-[(diethylamino)(thiocarbonyl)]benzamidoyl chloride and 2-mercaptophenol (HL1) and 2-mercaptoaniline (HL2) under C-S bond cleavage and formation of oxorhenium(V) and oxotechnetium(V) complexes with the resulting decomposition products 2-mercaptophenol and N-[(dialkylamino)thiocarbonyl]-N'-2-mercaptophenyl)benzamidine (H2L2a), respectively. The products, (NBu4)[ReO(S,O-C6H4)(2)], [ReOCl(L-2a)] and [TcO(L-2a)] were obtained in good yields and isolated in crystalline form. Single-crystal X-ray studies reveal square-pyramidal coordination environments with apical oxo ligands for all three product complexes under study.
