Synthesis and spectroscopic characterization of some sterically hindered ?-oxo bis [tricyclohexyl antimony (V)] carboxylates and -halocarboxylates
نویسندگان
چکیده
A series of sterically hindered μ-oxo bis [tricyclohexylantimony (V)] carboxylates [(cyclo-C6H11)3Sb-O-Sb(cycloC6H11)3](OCOR)2 where -OCOR = p-trifluoromethyl mandelate, p-methoxy mandelate, salicyclate, 2pyrazine carboxylate, mandelate has been synthesised and characterised by solid state infrared, H , Fand C NMR spectroscopy, molecular weight and conductance measurements. The newly synthesized derivatives are monomeric in benzene and non ionic in acetonitrile with pentacoordination dispensation around antimony. Keywords—μ-oxo bis [tricyclohexylantimony (V)] carboxylates, halocarboxylates, IR, H, F NMR, CNMR spectra, monomeric, non ionic. —————————— ——————————
