[ M OCl 4 ] – complexes ( M = Re, Tc) react with thianes derived from N ‐[(diethylamino)(thiocarbonyl)]benzamidoyl chloride and 2‐mercaptophenol (HL 1 ) and 2‐mercaptoaniline (HL 2 ) 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 (H 2 L 2a ), respectively. The products, (NBu 4 )[ReO(S,O‐C 6 H 4 ) 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.
