The title compound, [Pd(C26H45S4)Cl]·CH2Cl2, crystallizes with a disordered dichloromethane solvent molecule [occupancy ratio = 0.67 (4):0.33 (4)]. Two of the tert-butyl groups are also disordered [occupancy ratios = 0.70 (5):0.30 (5) and 0.63 (4):0.37 (4)]. Although the pincer ligand offers the possibility for coordination of two different metal atoms, the present structure shows only the coordination of a single PdII atom in a typical S-C-S tridentate pincer manner. The PdII atom is in a slightly distorted square-planar environment with the two tert-butylsulfanyl groups arranged in a trans conformation and with a chloride ligand trans to the -bonded aromatic C atom. The structure exhibits a durene-like ligand frame, forming a dihedral angle of 13.6 (4)° with the metal coordination (Pd/S/S/Cl/C) environment. It is noteworthy that the tert-butyl groups are found in a syn arrangement, this being different to that found previously by Loeb, Shimizu & Wisner [(1998). Organometallics, 17, 2324-2327].
