摘要：

Mononuclear complexes of formulae [LMCl2(HPRR')], [LMCl(HPR2)2]BF4 and [LM(acac)-(HPR2)]BF4 (M = Rh, Ir; L = C5Me5. M = Ru; L = p-Cymene; R = Ph, H; R' = H; Hacac = acetylacetone but not in all possible combinations) have been prepared from the corresponding [{LMCl}2(mu-Cl)2] or [LMCl(acac)] and HPRR'. Complexes [LMCl2(HPPh2)] [L = C5Me5; M = Rh (I), Ir (IV), L = p-Cymene; M = Ru (VII)] react with [M'(mu-OMe)(diolefin)]2 (M' = Rh; diolefin = tetrafluorobenzobarrelene (TFB), 1,5-cyclooctadiene (COD). M' = Ir; diolefin = COD) to yield diphenylphosphido-bridged complexes of formula [LMCl2(mu-PPh2)M'(diolefin)]. The structure of [(C5Me5)ClRh(mu-Cl)(mu-PPh2)Rh(COD)].1/2Et2O has been determined by X-ray diffraction methods. The complex consists of two moieties, (C5Me5)RhCl and Rh(COD), doubly-bridged by a diphenylphosphido group and a chlorine atom. The two rhodium atoms are separated by 3.3657(6) angstrom.
