Chlorido[2,3,5,6-tetra-kis-(tert-butyl-sulfanylmeth-yl)phenyl-?(3) S (2),C (1),S (6)]palladium(II) dichloro-methane monosolvate.

ABSTRACT: The title compound, [Pd(C26H45S4)Cl]·CH2Cl2, crystallizes with a disordered dichloro-methane solvent mol-ecule [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 Pd(II) atom in a typical S-C-S tridentate pincer manner. The Pd(II) atom is in a slightly distorted square-planar environment with the two tert-butyl-sulfanyl groups arranged in a trans con-formation 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].
