The reactions of with Na (R = alkyl or phenyl) give (I) when L = CO and I (II) when L is a tertiary phosphine, phosphite or stibine, or organo-isocyanide ligand.In similar reactions gives and PF6 forms .The iodide ligands in I may be displaced by L, to give II, or by other ligands such as ^-, ^-, H2O or pyridine whilst SnCl2 converts it to SnCl2I.The iodide counter-anion in II may be replaced by others to give ^-, ^- or ^- salts.However ^- acts differently and displaces (PhO)3P from (S2CNMe)>I to give which may be alkylated reversibly by MeI and irreversibly by MeSO3F to ⁺ salts.Conductivity measurements suggest that solutions of I in donor solvents are partially ionized with the formation of ⁺I^- species.The IR and 1H NMR spectra of the various complexes are reported.They are consistent with pseudo-octahedral pianostool molecular structures in which the bidentate dithiocarbamate ligands are coordinated to the metal atoms through both sulphur atoms.
