The crystal and molecular structure of Pd(SNNMe2)(AsPh3)Cl2 was determined from single-crystal X-ray diffraction data.In agreement with the structure previously proposed on the basis of IR data, the complex has the cis-configuration with the Me2NNS ligand S-bonded to the metal.It crystallizes in the space group P with a 9.407(2), b 10.540(2), c 12.265(4) Angstroem; α 68.1(1), β 78.3(1), γ 86.3(1) deg and Z = 2.The structure was refined to R = 0.029 for 2664 diffractometer data with I 3?(I).The palladium atom is in a nearly square planar coordination geometry with Pd-S 2.249(1), Pd-As 2.362(1), Pd-Cl(1) 2.313(1), Pd-Cl(2) 2.359(1) Angtroem.The very short Pd-S bond length may indicate a strong ? + ? synergistic interaction of the Pd atom with the N-thionitrosodimethylamine ligand.Me2NNS reacts with Pd(PhCN)2Cl2 to give, besides the known cis-Pd(SNNMe2)2Cl2, the complex 2> (IIIa), and an unstable compound which is probably Cl2.The stable salts (BPh4)2 (IVa) and HgCl4 (IVd) were obtained from this unstable compound and NaBPh4 or HgCl2.Alternatively the stable salts (PF6)2 (IVb) and PdCl4 (IVc) were obtained from Me2NNS and (PF6)2 (diene = 1,5-cyclooctadiene, norbornadiene) or Na2PdCl4.Me2NNS reacts with Pt(PhCN)2Cl2 to form an unstable compound probably Cl2 which was obtained in the stable form as Y2 (Y = BPh4 (Va), PF6 (Vb); Y2 = PtCl4 (Vc)).The complexes 2> (X = Cl (IIIa), Br (IIIb), SCN (IIIc), SeCN (IIId)) were prepared by reaction of Pd(PhCN)2Cl2 with Pd(SNNMe2)2X2.

MeNNS (Me=methyl) reacts with Pd(diene)Cl2 (diene=1,5-cyclooctadiene, norbornadiene, 1,3,5,7-cyclooctatetraene, dicyclopentadiene) to give Pd(Me2NNS)2Cl2 and with M(1,5-cyclooctadiene)Cl2 (M=PdII) in the presence of PR3 (PR3=PPh3, p-tolylPPh2)
