Di- and tri-metallic complexes containing two bridging cyclodiphosphazane ligands: the crystal structure of [MO2(CO)8{µ-cis-[PhNP(OC6H4Me-p)]2}2]

Abstract

The reactions of the mononuclear cyclodiphosphazane complexes, cis-[Mo(CO)4{cis-[PhNP(OR)]2}2] with [Mo(CO)4(nbd)](nbd = norbornadiene), [Mo(CO)4(NHC5H10)2] or [MCl2(cod)](cod = cycloocta-1,5-diene) afforded the homobimetallic complexes, [Mo2(CO)8{µ-cis-[PhNP(OR)]2}2](R = C6H4Me-p5 or CH2CF36) or the heterobimetallic complexes, [Mo(CO)4{µ-cis-[PhNP(OR)]2}2MCl2](R = C6H4Me-p; M = Pd 7 or Pt 8). In all the above complexes, the two metal moieties are bridged by two cyclodiphosphazane ligands. The reactions of the mononuclear complexes, cis-[M(CO)4(A){cis-[PhNP(OC6H4Me-p)]2}] with [M′Cl2(cod)] afforded the trinuclear complexes, cis-[M′Cl2[M(CO)4(A){cis-[PhNP(OC6H4Me-p)]2}]2](M′= Pd, M = Mo, A = P(OMe)310; M′= Pt, M = Mo, A = P(OMe)311; M′= Pd, M = W, A = NHC5H1012; M′= Pt, M = W, A = NHC5H1013). The structure of the complex 5 has been determined by single-crystal X-ray crystallography.
