Synthesis of Hydrazinium Metal Complexes

2 Solid-State Synthesis of Ammonium Vanadyl Complex 

Vanadium compounds have a complex chemistry because of the multiple oxidation states of vanadium. Among these, V2O5 is an important semiconducting material with potential applications as catalysts, chemical sensors, field effect transistors, and electrochemical and photochromism devices. Studies on the reactivity of hydrazinium chloride with NH4VO3 have led to the formation of the ammonium vanadyl complex (NH4)2VO (OH)2Cl2, which is a precursor to the formation of V2O5. 

Solid-state reactions between N2H5CI and NH4VO3 have been carried out in different mole ratios at 100 °C in air [4]. The DTA (differential thermal analysis) results of N2H5CI, NH4VO3 and N2H5CI NH4VO3 

The complex (NH4)2VO(OH)2Cl2 is thus a precursor to the formation of V2O5, an important semiconducting material.
