| Abstract: | Recent synthetic and structural studies on multiply bonded complexes of stoichiometry M2X4[μ-R2P(CH2)nPR2]2 (M = Mo, W or Re; X = Cl, Br or I; R = Me, Et or Ph; n = 1 or 2), the ditungsten(III) hydride W2(μ-H)(μ-Cl)Cl4(μ-dppm)2 (dppm = Ph2PCH2PPh2), Re2Cl4(μ-dmpm)3 (dmpm = Me2PCH2PMe2), and M2(μ-Cl)2 Cl4(μ-R2PCH2PR2)2 (R = Me or Ph) are surveyed. The first examples of multiply bonded complexes that contain the Ph2PCH CHPPh2 ligand (abbreviated dppee) are described, viz. the α- and β-isomers of M2X4(dppee)2 (M = Mo or Re, X = Cl or Br). The reactions of Re2X4(dppm)2 (X = Cl or Br) with RNC, RCN and CO ligands that yield complexes in which a metal-metal multiple bond is preserved are reviewed. |
