employed. The formation of the trinuclear complexes [Mo(CO)3(η2-NN)(X)]2Hg is favoured over the expected bimetallic derivatives, in which two metals are bridged by the dppm ligand. Bimetallic compounds are obtained when bulky ligands are present, such as dmp bonded to a molybdenum atom or I bonded to mercury, and only in the latter case is a MoHg complexbridged by dppm obtained.

The first, involving the reaction of [Mo(SnRCl2(Cl)(CO)3(CH3CN)2] (R Me, Ph) with PP-donor ligands [PP = 1,2-bis(diphenylphosphine)ethane, dppe; 1,3-bis(diphenylphosphine)propane, dppp] always gave rise to neutral seven-coordinate complexes of the type [Mo(SnRCl2)(Cl)(CO)3(η2-PP)] (I). On the other band, three types of compounds
Molybdenum tricarbonyl complexes containing unidentate diphosphine. NMR study of fac-mer isomers and crystal structure of fac-Mo(CO)3(η2-phen)(η1-dppm)
The preparation of Mo(CO)3(η2-NN)(η1-dppm) (NN = 2,2′-bipyridyl (bipy), 1,10-phenanthroline (phen), 2,9-dimethyl-1,10-phenanthroline (dmp); dppm = bis(diphenylphosphino)methane) by reactions of Mo(CO)4(η2-NN) with dppm have given a fac isomer or a fac-mer mixture depending on the nature of the NN ligand and on the reaction conditions. 1H, 13C and 31P NMRspectroscopy have been used for the characterization

A new synthetic route to heterobimetallic MRh (MMo or W) complexes has been explored. The procedure is the reaction of Rh1 complexes of the type [RhCl(diolefin)}2] (diolefin NBD or COD) with the complexes of monodentate dppm [M(CO)3(NN)(dppm-P)] (NN = phen or bpy), which are potential phosphine ligands.
已探索出一条新的合成途径来合成异双金属MRh(MMo或W)配合物。程序是[RhCl(di烯烃)} 2类型的Rh 1配合物(二烯烃NBD或COD)与单齿dppm配合物[M(CO)3(NN)(dppm-P)]的反应( NN = phen或bpy),它们是潜在的膦配体。

The ability of trimethylamine N-oxide as a chemical initiator for facile oxidative decarbonylation in metal carbonyls is manifested by the isolation of M(CO)3(η2-bipy)(η1-dppm) (where M Cr, Mo, W; bipy = 2,2′-bipyridyl; dppm = bis(diphenylphosphino)-methane). The synthetic strategy and spectral (IR and 1H and 31P NMR) characterisations are presented and discussed. Syntheses of the well-known M(CO)4(η2-bipy)
