Dithiocarbonate and Trithiocarbonate Complexes of Palladium(II); Crystal Structure of Pd(Ph3P)2(CS2O)· CH2Cl2

Di-and trithiocarbonate complexes of palladium(II) have been prepared by the action of O2 or S8 on PdL2(η2 -CS2) in the presence of excess L (L = phosphine ligand). 31P NMR data for Pd(PPh3)2(CS2O) are consistent with the presence in solution of both S̱,S̱ and S̱,O̱ coordinated dithiocarbonate. An X-ray crystal structure of the dichloromethane solvate [P1̄, a = 1103.6(4), b = 1343.4(5), c = 1368.5(5) pm, α = 94.77(3), β = 94.67(3), γ = 113.64(3)°, Z = 2, R = 0.059] suggests that an equivalent disorder may occur in the solid state.
