    Reaction of [Ml2(CO)3(NCMe)2] (M = Mo or W) with an excess of NCR (for M = W, R = Et, tBu, CH2Ph or Ph; for M = Mo, R = Ph) in CH2Cl2 at room temperature gives the nitrile-exchanged products [MI2(CO)3(NCR)2] (1–5). Equimolar quantities of 1–5 and L (L = PPh3, AsPh3 or SbPh3) react in CH2Cl2 at room temperature to afford the mixed ligand complexes [MI2(CO)3(NCR)L] (6–20). X-ray single crystallographic

The new metalloborane [6,6,6,6-(CO)3(PPh3)-6-W-B9H13] (1) and the previously reported [6,6,6,6-(CO)2(PPh3)2-6-Mo-B9H13] were isolable in low yield from the appropriate reaction mixtures. Complex 1 has been characterized by elemental analysis, IR spectroscopy and multielement (1H, 11B-1H} and 31P-1H}) NMR spectroscopy. In addition to 1, moderate yields of [NMe4][WI3(CO)3(PPh3)] and [4-(PPh3)B9H13]

  • Nido-6-metalladecaborane chemistry: Molecular structure and fluxionality of [6,6,6,6-(CO)2(PPh3)2-nido-6-WB9H13]

    The molecular and crystal structure of the nido-6-tungstadecaborane [6,6,6,6-(CO)2(PPh3)2-nido-6-WB9H13] (1) has been determined showing that the tungsten atom is incorporated into the 6-position of a nido 10-vertex (WB9) cage. The tungsten atom has a seven-coordinate capped trigonal prismatic environment and is bonded to two hydrogen and three boron atoms of the B9H13} cage, in addition to two CO groups and two PPh3 ligands. Variable-temperature (-90-degrees-C to +50-degrees-C) P-31H-1} NMR spectroscopy of 1 reveals that the exo-polyhedral ligands about the tungsten atom are fluxional with respect to PPh3 site exchange with an activation energy (DELTAG(double dagger) at the coalescence temperature (-73-degrees-C), of < 38 kJ mol-1.
