The crystal structure of the title compound, trans ‐[PtCl 2 (C 16 H 23 P) 2 ], has been determined at 100 K. The Pt atom is located on a twofold axis and adopts a distorted square‐planar coordination geometry. The structure is only the second example of a coordination complex containing a derivative of the 4,8‐dimethyl‐2‐phosphabicyclo[3.3.1]nonane (Lim) phosphine ligand family. The ligand contains four chiral C atoms, with the stereochemistry at three of these fixed during synthesis, therefore resulting in two possible ligand stereoisomers. The compound crystallizes in the chiral space group P 4 3 2 1 2 but is racemic, comprising an equimolar mixture of both stereoisomers disordered on a single ligand site. The effective cone angles for both isomers are the same at 146°.
