Thermal reactions of the olefin-molybdenum carbonyls C7H8Mo(CO)n(n= 4, C7H8= norbornadiene; n= 3, C7H8= cycloheptatriene) with RN (PF2)2 ligands (R = Me and Ph) in hydrocarbon solvents at 100–120 °C lead ultimately to binuclear complexes of the type [RN(PF2)2]nMo2(CO)11 – 2n(n= 3, 4, and 5); structure determinations by X-ray diffraction on [PhN(PF2)2]3Mo2(CO)5 and [MeN(PF2)2]4Mo2(CO)3 indicate the
烯烃钼羰基C 7 H 8 Mo(CO)n(n = 4,C 7 H 8 =降冰片二烯; n = 3,C 7 H 8 =环庚三烯)与RN(PF 2)2配体(R = Me和Ph)在100–120°C的烃溶剂中最终导致[RN(PF 2)2 ] n Mo 2(CO)11 – 2 n类型的双核络合物(n = 3、4和5) ; 由结构测定X上[PHN射线衍射(PF 2)2 ] 3 Mo 2(CO)5和[MeN(PF 2)2 ] 4 Mo 2(CO)3分别表示对称和不对称桥连羰基的存在。
