The title compound, [PdCl₂(C₂₁H₃₃P)₂], forms a monomeric complex with a trans-square-planar coordination geometry about the Pd^II atom which lies on an inversion centre. The Pd-P bond lengths are 2.3760 (13) Å, while the Pd-Cl bond lengths are 2.3172 (14) Å. The observed structure was found to be closely related to that of trans-dichloridobis[dicyclohexyl(phenyl)phosphane- [kappa] P]palladium(II), [PdCl₂{P(C₆H₁₁)₂(C₆H₅)}₂] [Burgoyne et al. (2012). Acta Cryst. E68, m404].
