With proven performance in transition metal and lanthanoid chemistry, pyrazolates have been established as viable MO-CVD precursors. Recent work in our and other laboratories is concerned with the development of synthetic strategies towards the alkaline earth metal pyrazolate target compounds, allowing their clean and efficient preparation. However, the thermal stability of the compounds, as evaluated by TGA and sublimation studies, showed that the majority of compounds decomposed upon heating, resulting in premature ligand loss. The poster will discuss our efforts to improve the thermal stability of the pyrazolate target compounds.
