MASS SPECTROSCOPIC (FAB-MASS) STUDIES OF CHROMIUM TRIOXIDE-ORGANIC ACID COMPLEXES

Abstract

In the present study complexes of chromium were prepared using CrO3,salicylic acid, benzoic acid and tertiary amyl alcohol as a solvent. Mass spectra (FAB-Mass) of solid samples were recorded. Mass spectra of Cr Complexes suggest that Complex of Cr/ben-TAA With molar ratio 1:1 (Cr/Hben/T/1) is probably monomeric and molar ratio 1:2 (Cr/Hben/T/2) is dimeric. Complexes of Cr/H2 sal-TAA with molar ratio 1:1 (Cr/H2 sal/T/1) and 1:2 (Cr/H2 sal/ T/2) are probably dimeric OH- bridged Cr (III) complexes.
