[The synthesis, 1H NMR and IR study of [(n-Bu)4N]2[Mo2O5(OC10H6O)2] and [(n-Bu)4N]2[Mo4O10 (OC10H6O)2(OCH3)2]].
The title organo-molybdate derivatives are synthesized and their IR, 1H NMR spectra have been determined and the relations between the structures and the 1H NMR and IR parameters have been studied. The results indicate that the red shift of the IR frequency of Mo-O-Mo in [(n-Bu)4N]2[Mo2O5(OC10H6O)2] (complex I) takes place to compare with that in [(n-Bu)4N]2[Mo4O10 (OC10H6O)2(OCH3)2] (complex II) and lower filed shift of 1H NMR of the aromatic H atoms in complex II occurs as contrasted to that in the complex I. It is found also the organo-molybdate derivatives are very sensitive to the acidity of the chemical system.
