Abstract In this review are analyzed and classified crystallographic and structural parameters of P(0)P3, Pt(0) P4 and Pt(II)P4 derivatives – distortion isomers. Some of the isomers are differing not only by degree of distortion but also by crystal class. There are three types of organo-phosphines which build up the respective geometry about the platinum atoms. In Pt(0)P3 a distorted trigonal planar geometry is build up by three monodentate PPh3 ligands. In Pt(0)P4 a tetrahedral geometry with various degree of distortion is build up by a pair of homo-bidentate ligands. In Pt(II)P4 isomers a square-planar geometries with various degree of distortion are build up by bidentate-P,P’donor ligands, (except one example of isomers, where a tetradentate is involved). The bidentate-P,P’-donor ligands form: four-(PNP,PCP), five-(PC2P) and six-(PC3P) metallocyclic rings. The tetradentate forms five-(PC2P). There are some cooperative effects between Pt–P bond distances and the metallocyclic rings, and at the same time a distortion of the respective geometry increases.

Pt(0)P3、Pt(0)P4 和 Pt(II)P4 的结构——畸变异构体

摘要 在这篇综述中，对 P(0)P3、Pt(0)P4 和 Pt(II)P4 衍生物——畸变异构体的晶体学和结构参数进行了分析和分类。一些异构体不仅因变形程度而异，而且因晶体类别而异。存在三种类型的有机膦，它们构成了关于铂原子的​​相应几何结构。在 Pt(0)P3 中，扭曲的三角形平面几何结构由三个单齿 PPh3 配体构成。在 Pt(0)P4 中，具有不同程度变形的四面体几何结构由一对同二齿配体构成。在 Pt(II)P4 异构体中，具有不同变形程度的方形平面几何形状由双齿 P,P' 供体配体构成（除了异构体的一个例子，其中涉及四齿）。双齿-P,P'-供体配体形式：四-(PNP,PCP)，五（PC2P）和六（PC3P）金属环。四齿形成五-(PC2P)。Pt-P 键距和金属环之间存在一些协同效应，同时各自几何结构的畸变增加。
