6-iPr2Ph) afforded a series of paramagnetic oxo and imido Mo(V) complexes depending on the nature of the solvent used in each case. A X-ray study of one of this complexes, MoCl3(NAr)L2 (L=N-2',6'-diisopropyl phenyl-2,5-dimethyl benzamide) (3) (orthorhombic, P212121, a=10.8194(8), b=23.528(2), c=23.914(2) Å, V=6087.4(9) Å3, Z=4) supports a pseudooctahedral structure with the imido group occupying one of the
MoCl 4(O)与ArNCO(Ar = 2,6- i Pr 2 Ph)的反应产生了一系列顺磁性羰基和亚氨基Mo(V)络合物,具体取决于每种情况下所用溶剂的性质。此复合物之一的MoCl 3(NAr)L 2(L = N-2',6'-二异丙基苯基-2,5-二甲基苯甲酰胺)(3)的X射线研究(斜方晶,P 2 1 2 1 2 1,一个= 10.8194(8),b = 23.528(2),C ^ = 23.914(2)埃,V = 6087.4(9)埃3,ž= 4)支持亚胺基占据轴向位置之一的伪八面体结构。在三当量的P(OMe)3存在下还原Mo(VI)和Mo(V)的羰基和亚氨基配合物会产生MoCl 2(E)[P(OMe)3 ] 3(E = O(5), NAr(6))。5和6的光谱数据显示伪八面体结构,其中oxo或亚氨基配体占据轴向位置之一,而三个亚磷酸酯配体位于赤道平面。配合物5和6 与3,3-二苯基
