Abstract
Reactions of arsenic trichloride and 2‐chloro‐1,3,2‐dioxarsolane or ‐dioxarsinane, sC1 (G=-CH2CH2- or -CH2CH2-CH2-), with sodium salt of O,O′‐bis(ortho‐, meta‐ or para‐tolyl) dithiophosphate ligands, (o‐, m‐ or p‐ MeC6H4O)2PS2Na, in different molar ratio in toluene under anhydrous conditions results in the formation of complexes corresponded to [{(o‐, m‐ or p‐MeC6H4O)2PS2}nAsCl3‐n] (n=1 or 2) and [(o-, m- or p- MeC6H4O)2
(n=2 or 3) in 83–93% yield. These yellow complexes were characterized by elemental analysis, molecular weight determinations, IR and NMR (1H, 13C and 31P) spectroscopic studies, which revealed monomeric nature of the complexes and anisobidentate mode of bonding of dithio moiety with arsenic atom, leading to a trigonal bipyramidal or octahedral geometry.
