In the title complex, trans-[PtCl2{P(C6H11)2(4-Me2NC6H4)}2]·2CH2Cl2, the PtII atom is located on an inversion centre, resulting in a trans-square-planar geometry. Important geometric parameters are the Pt-P and Pt-Cl bond lengths of 2.3258 (6) and 2.3106 (6) Å, respectively, and the P-Pt-Cl angles of 89.64 (2) and 90.36 (2)°. The effective cone angle for the dicyclohexyl[4-(dimethylamino)phenyl]phosphane unit was calculated to be 164°. The compound crystallizes with two dichloromethane solvent molecules; one of which is severely disordered and was treated using the SQUEEZE routine in PLATON [Spek (2009[Spek, A. L. (2009). Acta Cryst. D65, 148-155.]). Acta Cryst. D65, 148-155].
