Abstract A method for the preparation of (C 6 H 5 ) n PX 3- n Cr(CO) 5 complexes in the crystalline state is described. The carbon-oxygen stretching vibration, v CO ( A , eq.), of the complexes with X = Cl, Br, I is mainly determined by the inductive effect of the (C 6 H 5 ) n PX 3- n group. For X = H, the v CO band is defined by the concomitant influence of the σ, π and steric effects.
摘要 描述了一种制备晶态(C 6 H 5 ) n PX 3-n Cr(CO) 5 配合物的方法。X = Cl, Br, I 的配合物的碳-氧伸缩振动 v CO ( A , eq.) 主要由 (C 6 H 5 ) n PX 3-n 基团的诱导效应决定。对于 X = H,v CO 带由 σ、π 和空间效应的伴随影响定义。
