用~（19）F、~（17）O和~（49）Ti NMR研究了NH_4TiOxF_（5 - 2 x）（x≤0.4）（Ⅰ）的水解反应。配合物I与水的相互作用伴随着[TiF 6]2-和多核钛形式的形成。已经确定了I水解产生的主要形式的组成。钛八面体通过形成羟基桥键合成二聚体和其他低聚物，从而显著降低溶液的pH。发现标题配合物的水解与四氟化钛的水解有密切的相似性。
Hydrolysis of NH4TiOxF5-2x(x≤0.4) (I) was investigated by19F,17O, and49Ti 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.
