The sol-gel processing of simple oxides such as SiO{sub 2} and TiO{sub 2} is relatively well understood and can be approached in a systematic fashion, since the corresponding alkoxide precursors Si(OR){sub 4} and Ti(OR){sub 4} are known and their chemistry has been studied in detail. Operating on the hypothesis that the sol-gel processing of BaTiO{sub 3} might be similarly simplified if the analogous alkoxide precursors BaTi(OR){sub 6} were available, the authors have attempted to prepare such complexes and study their chemistry. In the course of these investigations, it was found that the problems associated with the preparation of alkyl BaTi(OR){sub 6} complexes can be circumvented using aryl derivatives, and the authors report here the synthesis and characterization of the solvated phenoxide BaTi(OC{sub 6}H{sub 5}){sub 6}{center_dot}2DMF, DMF = N,N-dimethylformamide, a viable sol-gel precursor to BaTiO{sub 3} gels, powders, and thin films. 15 refs., 2 figs.
