Chlorido[2,3,5,6-tetra­kis­(tert-butyl­sulfanylmeth­yl)phenyl-κ³S²,C¹,S⁶]palladium(II) dichloro­methane monosolvate

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 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-butyl­sulfanyl groups arranged in a trans con­formation and with a chloride ligand trans to the σ-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].

cis-Bis(O-methyl­dithio­carbonato-κ²S,S′)bis­(tri­phenyl­phosphane-κP)ruthenium(II)

In the title compound, [Ru(CH₃OCS₂)₂(C₁₈H₁₅P)₂], the Ru^II atom is in a distorted octa­hedral coordination by two xanthate anions (CH₃OCS₂) and two tri­phenyl­phosphane (PPh₃) ligands. Both bidentate xanthate ligands coordinate the Ru^II atom with two slightly different Ru—S bond lengths but with virtually equal bite angles [71.57 (4) and 71.58 (3)°]. The packing of the complexes is assured by C—H...O and C—H...π inter­actions.
