Synthesis of Zirconium Pinacolate and Mechanism of Its Thermal Transformation to ZrO2:  Impact of a Vicinal Diol Ligand

Synthesis of Zirconium Pinacolate and Mechanism of Its Thermal Transformation to ZrO2:  Impact of a Vicinal Diol Ligand

Reaction of Zr2(OiPr)8(HOiPr)2 with a slight excess of pinacol (HOCMe2CMe2OH) yields Zr2(OCMe2CMe2O)2(OCMe2CMe2OH)4, as confirmed by X-ray crystallography. Inter- and intramolecular hydrogen bonding results in the polymeric solid-state structure and the subsequent nonvolatility and reduced solubilit...

Zusammenfassung:Reaction of Zr2(OiPr)8(HOiPr)2 with a slight excess of pinacol (HOCMe2CMe2OH) yields Zr2(OCMe2CMe2O)2(OCMe2CMe2OH)4, as confirmed by X-ray crystallography. Inter- and intramolecular hydrogen bonding results in the polymeric solid-state structure and the subsequent nonvolatility and reduced solubility of the species. The thermal transformation of zirconium pinacolate occurs in two distinct steps, as seen by the thermal gravimetric analysis (TGA), and occurs at
