摘要：

Hydrolysis of NH4TiOxF5-2x (x less than or equal to 0.4) (I) was investigated by F-19, O-17, and Ti-49 NMR. The interaction of complex I with water is accompanied by the formation of [TiF6](2-) and multinuclear titanium forms. The composition of the main forms resulting from hydrolysis of I has been established. The bonding of titanium octahedra into dimers and other oligomers occurs by formation of hydroxyl bridges, considerably lowering the pH of the solution. Close analogy has been found between hydrolysis of the title complex and that of titanium tetrafluoride.
