The molybdenum(IV) oxo-complexes [MoOCl2(PR″3)3](PR″3= PMe2Ph or PEt2Ph) react with the substituted hydrazines RCONHNHR′(R = Ph, p-ClC6H4, p-MeC6H4, p-MeOC6H4, Et, Prn, Pri, or CH2Ph; R′= Ph, p-ClC6H4,p-MeOC6H4, 1-C10H7, or Me) to give the imido-complexes [MoCl2(NR′)(R′N2COR)(PR″3)]. The crystal and molecular structure of the title complex has been determined from single-crystal X-ray diffractometer
钼(IV)氧配合物[MoOCl 2(PR” 3)3 ](PR” 3 = PMe 2 Ph或PEt 2 Ph)与取代的肼RCONHNHR'(R = Ph,p -ClC 6 H 4,p -MeC 6 H 4,p -MeOC 6 H 4,Et,Pr n,Pr i或CH 2 Ph; R'= Ph,p -ClC 6 H 4,p -MeOC 6 H 4,1-C 10 ħ 7,或Me),得到亚氨基配合物[代替MoCl 2(NR')(R'N 2 COR)(PR“ 3)]。标题配合物的晶体和分子结构已经由单晶X射线衍射仪数据确定。晶体是单斜晶体,a = 8.995,b = 19.090,c = 17.860Å,β= 104.15°,空间群P 2 1 / c,Z = 4。使用2279个独立观察到的反射对正方形进行细化已达到R= 0.066。配合几何是八面体变形的。金属-二烯螯合物体系相当平坦,键长表明螯合物环
