The i.r. spectra (4000-90 cm−1) of the [Pt(Him)4]X2 complexes (Him = imidazole, X = Cl, Br or I) andcis- andtrans-[Pt(Him)2X2] (X = Cl, Br, I or NO2) and their D3-labelled analogues have been determined. The distinction between the ring and C-H (or N-H) modes of imidazole is based on the relative shifts which these bands undergo on D3-labelling. Assignments, based on the effects of imidazole deuteriation
[Pt(Him)4]X2 配合物(Him =
咪唑,X = Cl、Br 或 I)和顺-反-[Pt(Him)2X2] (X = Cl 、Br、I 或
NO2) 及其 D3 标记的类似物已被确定。
咪唑的环和 CH(或 NH)模式之间的区别是基于这些带在 D3 标记上经历的相对位移。根据
咪唑氘化和卤化物取代的影响,为 v(Pt-Him) 和 v(Pt-X) 模式提供了分配。
