HYDROXAMIC ACID DINUCLEAR COMPLEXES OF MOLYBDENUM(V) AND MOLYBDENUM(III)

Molybdenum(V) and molybdenum(III) complexes [Mo2O3L4] and [Mo2L6] derived from hydroxamic acids (HL) were prepared and identified by Raman, i.r., e.s.r., electronic spectra and analytical data. The low magnetic moments of the dinuclear complexes are due to in part to intramolecular interactions. Electronic spectra and vibrational studies indicate the presence of a Mo2O3 core in the molybdenum(V) complexes. The relative intensities of the main and satellite peaks in e.s.r. spectra indicate the dinulcear nature of molybdenum(III) hydroxamates.
