| Abstract: | Reactions of monooxidized thioyl and selenoyl bis(phosphanyl)amine ligands C10H7‐1‐N(P(E)Ph2)(PPh2) E = S ( 1 ), Se ( 2 )] with Mo(CO)4(pip)2 and W(CO)4(cod) afforded the complexes M(CO)4{ 1 ‐κ2P,S}] M = Mo ( 3 ), W ( 4 )] and M(CO)4{ 2 ‐κ2P,Se}] M = Mo ( 5 ), W ( 6 )]. Complexes 3 – 6 were characterized by multinuclear NMR (1H, 13C, 31P, and 77Se NMR) and IR spectroscopy. Crystal‐structure determinations were carried out on 3 , 5 , and 6 , which represent the first examples of structurally characterized complexes of such ligands with group‐6 metal carbonyls. |
