Abstract

The reaction of silver(I) iodide with tri(p-tolyl)phosphine in MeCN solution in 1:3 molar ratio yields a polymorph of the complex of the formula [AgI{P(4-MeC6H4)3}3], with the Ag atom in a distorted tetrahedral environment. A polymorphic structure of this complex (a) is compared with previously published crystal structures (b), determined at different temperatures. The two polymorphs are compared using r.m.s. overlay calculations as well as half-normal probability plots.

摘要

碘化银（I）与三（对甲苯基）膦在乙腈溶液中按1:3的摩尔比反应，生成分子式为[AgI{P(4-MeC6H4)3}3]的配合物的一种多晶型物，其中银原子处于扭曲的四面体环境中。将该配合物的一种多晶型结构（a）与先前在不同温度下测定的已发表晶体结构（b）进行比较。使用均方根叠加计算以及半正态概率图对这两种多晶型物进行比较。
