Sterically Hindered Organoantimony Compounds of TRIS (α-NAPHTHYL) Antimony (III)(α-C₁₀H₇)_nSbX_3-n(n=1,2) & TRIS (α-Naphthyl) Antimony (V) ( α-C₁₀H₇)_nSbX_5-n (n=2,3,4) Derivatives

Abstract: Several new hitherto unreported penta-coordinate tris ( & alpha; -naphthyl) - antimony (iii) & antimony (v) halothiocyanato, Interpseudohalide, Interhalogen of the general formulas ( & alpha; -C₁₀H₇) _nSbX_3-n and ( & alpha; -C₁₀H₇) _nSb_5-n (n=1, 2 where OOCR = C₆H₅CONHCH₂COO-, C₆H₄ (OH) COO-, C₆H₅C₂H₄COO-, (C₆H₅) ₂ (OH) C. COO, etc. X=halogens) have been prepared by the metathesis reaction of ( & alpha; -C₁₀H₇) _nSbX_3-n with the appropriate metals salts of the carboxylic acid. The halothiocyanate derivatives were also obtained by the addition of the tris ( & alpha; -naphthyl) -antimony (iii) & antimony (v). The newly synthesized compounds have been characterised by conventional methods. The failure to replace the second halogen atom in ( & alpha; -C₁₀H₇) _nSbX_3-n may be attributed to steric hindrance offered by the naphthyl groups bound to antimony as well as the bulky nature of the organic ligand.

Keywords: Tris &alpha, -naphthyl - antimony iii & antimony v, Halothiocyanato, Interpseudohalide, Interhalogen, Carboxylate
