All the ligands and complexes have been characterized with ~1H-NMR, MS and EA.X-Ray single crystal diffraction reveals that zirconium complex containing the tert-butyl substituted N_2O_2 ligand is an oxo- and hydroxyl-bridged dinuclear structure, which is possibly formed by partial hydrolysis of chlorides at one of the zirconium centers. A tetranuclear zirconium complex has been obtained and chacaterized, which is formed by complete hydrolysis of the chlorides at the zirconium centers.

The glass and crystalline glass-solders of Li2O-ZnO-SiO2 system were prepared by conventional melt technology. The various factors effecting on glass ceramics and glass were investigated,which include glass chemical composition and heat-treatment and so on. And then by means of XRD, DTA, IR and SEM, the structure and properties of the glass and glass-ceramic were studied. The coefficient of linear expansion , transform temperature and soft temperature wer measured. And then the factors that effect the mechanical strength of glass-ceramic were discussed and the fluxion property was determined and the crystallization course and mechanism were discussed, which can provide certain therial reference value for practice producing and glass seals to glass, ceramics and metal.
