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 O 2 or S 8 on PdL 2 (η 2 -CS 2 ) in the presence of excess L (L = phosphine ligand). 31 P NMR data for Pd(PPh 3 ) 2 (CS 2 O) 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.
