The reaction of sodium chloropalladate(II) with potassium N,N-di-n-propylthiocarbamate, K(SCONR2), affords Pd2(SCONR2)4(A) or NaHPd(SCONR2)4(D) depending on the metal to ligand ratio. D is converted to trans-Pd(SCONR2)2(NHR2)2(B) in 2-propanol. Reactions of A, B, and D with triphenylphosphine convert these into trans-Pd(SCONR2)2(PPh3)2(C). The structures of B-D have been determined by X-ray diffraction. D (C28H57N4NaO4PdS4, monoclinic, a = 14.953 (3) Å, b = 15.244 (9) Å, c = 16.968 (4) Å, β = 98.70 (2)°, Z = 4, P21/n) is a dimer with Pd in a planar PdS4environment. The two sodium atoms are hexacoordinated, and two NaO5(Pd) polyhedra are joined by two oxygen atoms via an inversion center. The structure of C (C50H58N2O2P2PdS2, monoclinic, a = 9.847 (2) Å, b = 20.454 (7) Å, c = 12.215 (3) Å,β = 101.19 (2)°, Z = 2, P1/n) contains two sulfur-bound monodentate R2NCOS ligands in a trans arrangement. Hydrogen bonding between the H atoms of the diisopropylamine ligands on the carbonyl oxygen atoms has been detected in the structure of B (C26H58N4O2PdS2, triclinic, a = 9.196 (7) Å, b = 9.982 (9) Å, c = 10.682 (10) Å, a = 86.79 (7)°, β = 74.64 (7)°, 7 = 64.80 (7)°, Z = 1, P1).
