以二氯β－二酮及其酯为配体的七种金属配合物Ｔｉ（ａｃａｃ）２Ｃ１２，Ｔｉ（ｂｚａｃ）２Ｃ１２， Ｓｎ（ｂｚａｃ）２Ｃ１２，Ｚｒ（ｂｚａｃ）２Ｃ１２，Ｔｉ（ｂｚｂｚ）２Ｃ１２，Ｔｉ（ｅｔａｃ）２Ｃ１２，Ｔｉ（ｍｅｓａ）２ＣＩ２ 有基本相似的质谱断裂途径：分子离子Ｍ＋较弱（＜６％），由Ｍ＋优先生成（Ｍ－ Ｃ１）＋．并能进一步断裂生成次级碎片离子，其中β－二酮酯类配体以六员环转移反应 为其特征，从Ｍ＋脱除β－二酮配体部分生成明显的特征离子。此外，由配体部分 可直接产生强的■离子（ＣＨ３Ｃ三０■，Ｃ６Ｈ５Ｃ三０■）和Ｃ６Ｈ＋５离子，据此总结 出上述配合物的基本断裂模式，并对由 Ｔｉ（ｂｚａｃ）２Ｃ１２和 Ｔｉ（ｂｚｂｚ）２Ｃ１２产生的例 外Ｃ６Ｈ＋６峰与红外（ＩＲ）与顺磁（ＥＳＲ）谱进行了比较。
Seven kinds of metal complexes Ti (acac) 2C12, Ti (bzac) 2C12, Sn (bzac) 2C12, Zr (bzac) 2C12, Ti (bzbz) 2C12 (Etac) 2C12 and Ti (mesa) 2Cl2 have similar mass spectrometric fragmentation pathways: the molecular ion M + is weak (<6%) and M + is preferentially (M- C1) +. And further rupture to generate secondary fragment ions. Among them, β-diketonate ligands are characterized by six-membered ring transfer reaction, and some β-diketone ligands are removed from M + to generate obvious characteristic ions. In addition, the strong part ions (CH3C3O3, C6H5C3O3) and C6H + 5 ions can be directly generated from the ligands. Based on this, the basic fracture modes of the above complexes are summarized and the complex structure of Ti (bzac) 2C12 and Ti Exceptional C6H + 6 peaks from (bzbz) 2C12 were compared to infrared (IR) and paramagnetic (ESR) spectra.
