Preparation of oxide materials from metal alkoxides

Abstract: This review covers the works on the sol-gel preparation of oxides from metal alkoxides that were carried out at the Faculty of Chemistry, Moscow State University, and at the Karpov Research Institute of Physical Chemistry. The composition and properties of the oxide powders and films prepared were considered in relation to the nature of alkoxides and solvents and complex formation in solution. The morphology and phase composition of the powders were examined in relation to hydrolysis conditions. Electrical and optical data are presented for titanate, zirconate, niobate, and tantalate powders, ceramics, and films

A novel family of structurally characterized lithium cobalt double aryloxides and the nanoparticles and thin films generated therefrom

Abstract: The reaction between LiN(SiMe3)2 and Co(N(SiMe3)2)2 in THF followed by the addition of an aryl alcohol (HOAr) yielded: [Co[(μ-OAr)2Li(THF)x]2 [where x = 2: OAr =: OC6H4Me-2 (oMP, 1), OC6H4(OCHMe2)-2 (oPP, 2), OC6H3(Me)2-2,6 (DMP, 3); where x = 1: OAr = OC6H3(OCHMe2)2-2,6 (DIP, 4)]. Undertaking the same synthesis in pyridine (py) led to the same general structure with py molecules substituted for the THF solvent molecules: [Co[(μ-OAr)2Li(py)2]2 (OAr = oMP (5), oPP (6)]. For 1−6, the tetrahedrally (Td) bound Co atom bridges two OAr ligands to each of the Li atoms. The Li atom adopts a Td or trigonal bipyramidal (TBP) geometry, as determined by the number of bound solvent molecules. For the more sterically demanding ligands with py as the solvent, the mononuclear monometallic species [Co[(μ-OAr)2(py)x]2 (OAr = DMP (7), x = 2; DIP (8), x = 3) were observed adopting a Td or TBP geometry, respectively, based on the number of bound solvent molecules. Increasing the steric bulk of the OAr to OC6H3But2-2,6 (D...
