  Mono- and di-bridged heterobimetallic systems from group 5 hydride phosphido and hydride phosphino metalloligands. Crystal structure of Cp2Ta(H)( μ-H)( μ-PMe2)Cr(CO)4

  摘要：

  The trihydrides Cp2MH3 (M=Nb, Ta) react with chlorophosphines PR2Cl (R=Me, Ph) affording phosphonium salts [Cp2MH2(PR2H)](+), Cl- (2 (a, b) 2' (a, b)). Depending on the metal (Nb or Ta) and on the nature of the phosphine substituent (Me or Ph), deprotonation of these salts leads to hydride phosphino Cp2MH(PR2H) (3 (a, b) 3'a) or hydride phosphido Cp2TaH2(PPh2) (4'b) metalloligands. These two kinds of complexes are able to bind [M'(CO)(5)] or [M'(CO)(4)] (M' = Cr, Mo, W) organometallic fragments to give mono-or di-bridged heterobimetallic systems. The crystallographic analysis of Cp2Ta(H)(mu-H)(mu-PMe2)Cr(CO)(4) (7'aCr) is reported and discussed. (C) 1997 Elsevier Science S.A.
