Abstract

The crystal structures of PdCl~2~[(−)‐DIOP], PtCl~2~[(−)‐DIOP] and of NiCl~2~‐[(−)‐DIOP] have been determined by X‐ray analysis and refined by least‐squares methods [(−)‐DIOP=(−)‐2,2‐dimethyl‐4,5‐bis(diphenylphosphinomethyl)‐1,3‐dioxolane]. The coordination around the nickel atom is tetrahedral, the coordination around palladium and platinum is square planar. The unit cell of the palladium complex contains two non‐equivalent molecules with different conformations of the seven‐membered chelate ring involving the metal and the two phosphorus atoms. PtCl~2~[(−)‐DIOP] is isostructural with the corresponding palladium complex.
