Methylenverbrückte Antimon(III)-dithiocarbamate, -xanthogenate und -dithiophosphate: [SbL2]2CH2 (L = S2CNR2, S2COR,S2P(OR)2)

Methylene-bridged Antimony(III)-dithiocarbamates, -xanthogenates, and -dithiophosphates: SbL₂]₂CH₂(L = S₂CNR₂, S₂COR, S₂P(OR)₂) 1 :4-reaction of Cl₂Sb]₂CH₂ with sodium dithiocarbamates, -xanthogenates or -dithiophoshates lead to the replacement of the chlorine atoms by the respective 1,1-dithio ligands. The products of the type SbL₂]₂CH₂ (L = S₂CNR₂, S₂COR, S₂P(OR)₂) are studied by IR, ¹H-NMR- and ¹³C-NMR-spectroscopy. Both spectral data and thermal stability of the compounds are compared with those of the corresponding monomethylstibanes MeSbL₂.
