The title compound, [PdCl2(C21H12F9P)2]·CH2Cl2, crystallizes with two independent complex molecules (each having the Pd(II) atom situated on an inversion centre) and a dichloro-methane molecule in the asymmetric unit. The independent Pd(II) atoms are in perfectly linear orientations of the ligands in mutually trans positions, but distortions of the Cl-Pd-P angles ranging from 86.151 (19) to 93.849 (19)° are evident. The effective cone angles for the tris-[4-(trifluoro-meth-yl)phen-yl]phosphane ligand were calculated to be 159 and 161°. In the crystal, weak C-H⋯Cl/F inter-actions create a three-dimensional supramolecular network. Loose packing at two of the -CF3 groups resulted in large thermal vibrations which were treated as two-component disorders [occupancy ratios 0.50:0.50 and 0.628 (15):0.372 (15)].
