制备

与原本的制备方法类似,[7][8]硝酸钛可以由五氧化二氮[9]硝酸氯[10]四氯化钛反应制得。[4]

水合硝酸钛 [Ti(H2O)6](NO3)3则可以由钛化合物溶于硝酸中而成。[11]

结构

硝酸钛的对称群是D2d,有四个二齿的硝酸根配体,其中的N-O键长为1.29 Å(配位)和1.185 Å(非配位)。[6]

性质

硝酸钛可溶于非极性溶剂四氯化硅和四氯化碳。[12][8]

硝酸钛具有吸湿性,会转化为不明确的水合物。[13]无水硝酸钛的反应性很高,甚至会和碳氢化合物反应。[13]它也会和正十二烷[14]对二氯苯苯甲醚联苯反应。[14][15]

硝酸钛受热分解成二氧化钛[16]
