The nickel and platinum complexes [MX2(dppe)] (X = Cl, Br) react with bi- and tri-valent metal diethyldithiocarbamates [M′(S2CNEt2)n] (M′ = Pb, Zn, Cd, Hg, Ni, MoO2, VO, n = 2; M′ = Co, Fe, Mn, n = 3) to afford salts [M(S2CNEt2)(dppe)]2[M′X4]; reactions involving [Cu(S2CNEt2)2] and [Ag(S2CNEt2)] gave salts of the form [M(S2CNEt2)(dppe)][M′X2] (M′ = Cu, Ag). The complexes cis [RuCl2(dppm)2], [CoCl2(dppe)] and [PdX2(bipy)] likewise react with the same dithiocarbamates to form salts [Ru(S2CNEt2)(dppe)2]2 [M′Cl4] [Co(S2CNEt2)2(dppe)]2 [M′Cl4] and [Pd(S2CNnBu2)(bipy)]2 [M′X4], respectively. Sample reactions involving other S-chelate ligands - S2COEt-, S2PPh2- and S2P(OEt)2- - appear to follow the same general pattern. However, the O-ethyldithio carbonates (ethylxanthates) are partly converted to the corresponding dithiocarbonates. An anomalous reaction between [CoCl2(dppe)] and [Zn(S2CNEt2)2] in the presence of (S2CNEt2)2 affords the novel complex [Co(S2CNEt2)2(dppe)]2[Cl 3ZnO:(Ph)2PCH2CH2P(Ph) 2:OZnCl3]. A selection of these salts have been fully characterised by elemental analysis and spectroscopic techniques, the remainder have been identified by spectroscopic methods alone. X-ray crystal structures are reported for the salts [Ni(S2CNEt2)(dppe)]2 [HgBr4], [Pt(S2CNEt2)(dppe)]2[CdCl4], [Co(S2CNEt2)2(dppe)]2[Cl 3ZnO:(Ph)2PCH2CH2P(Ph) 2:OZnCl3] and [Pd(S2CNnBu2) (bipy)]2[CdCl4].
