Abstract
Abstract Organotin derivatives of dimethyldithioarsinic (dithocacodylic) acid have been obtained from the appropriate organotin chloride and the sodium salt of the latter. Tin(IV) chloride and NaS 2 AsMe 2 · 2 H 2 O yielded only two products, namely Cl 2 Sn(S 2 AsMe 2 ) 2 and Sn (S 2 AsMe 2 ) 4 , regardless of the reagent ratio. Spectroscopic characterization of the compounds (infrared and 1 H NMR) provides structural information suggesting that the dimethyldithioarsinato group behaves as monodentate (or anisobidentate) ligand in Me 2 Sn(S 2 AsMe 2 ) 2 , Bu 2 Sn-(S 2 AsMe 2 ) 2 and Cy 3 Sn(S 2 AsMe 2 ), as bidentate in Ph 2 Sn(S 2 AsMe 2 ) 2 , Ph 3 Sn(S 2 AsMe 2 ) and Cl 2 As(S 2 AsMe 2 ) 2 , whereas Sn(S 2 AsMe 2 ) 4 contains both mono- and bidentate ligands, presumably in a six-coordinate structure.
