Spectral studies on the reaction of chromium (VI) compounds with aminophosphonic esters

Abstract

The studies on reaction of newly obtained aminophosphonic acid diethyl ester derivatives of fluorene with Cr2O72−, CrO42−, CrO3Cl− and CrO3 have been investigated using electronic, infrared,Raman and NMR spectral methods. It has been found that the resulting compounds are of the type (AH)2Cr2O7, whereA stands for the organic part of the molecule. The organic cation and solvent effects on the electronic states of pseudotetrahedrally arranged Cr(VI) anions are discussed.
