Abstract: In the title compound, [PdCl₂(C₂₇H₂₆P₂)] or PdCl₂[(C₆H₅)₂PCH₂P(C₆H₄CH₃)₂], the palladium center has a distorted square-planar geometry. There are two crystallographically independent molecules in the asymmetric unit. The dihedral angle between the PdP₂ and PdCl₂ planes is 2.95 (4)° in one independent molecule and 5.15 (4)° in the other. The P-Pd-P and P-C-P bond angles are significantly distorted because of the small bite angle of the chelating (bisphosphino)methane ligand. The steric demands of the substituted rings in the mixed ligand cause a slight elongation of the Pd-P(C₆H₄CH₃)₂ bond relative to the Pd-P(C₆H₅)₂ bond. In one molecule the tolyl ring shows positional disorder in a 0.58 (2):0.42 (2) ratio, in the other molecule the phenyl ring shows positional disorder in a 0.838 (9):0.162 (9) ratio.
