Two new structural type of binuclear platinum(0) complexes of formula [Pt2(µ-R2PCH2PR2)3(PPh3)], (2), and [Pt2(µ-R2PCH2PR2)3(PPh3)2], (3), have been characterized by n.m.r. spectroscopy and, for (2; R = Me), by X-ray crystallography; steric requirements of R determine the preferred structure and complexes (2; R = Me or Et) are shown to contain both 3-co-ordinate and 4-co-ordinate platinum(0) centres.
两种新结构类型的双核铂(0)配合物,其分子式为 [Pt2(µ-R2PCH2PR2)3(PPh3)], (2) 和 [Pt2(µ-R2PCH2PR2)3(PPh3)2], (3),具有经核磁共振表征。光谱学,对于(2;R = Me),通过X射线晶体学; R 的空间要求决定了优选的结构,并且配合物(2;R = Me 或 Et)显示出同时包含 3 配位和 4 配位铂(0)中心。
