合成了两种55-氯水杨酸铬(III)配合物[Cr(III)(55-Cl-SA)(en)22]Cl•22CH33OH•22H22O (I)和[Cr(III)(55-Cl-SA)(TETA)]- ClO44•H22O (II)，, (55-Cl-SA=＝55-氯-水杨酸，, en=＝乙二胺，, TETA=＝三乙烯四胺)，, 利用X射线晶体衍射和元素分析进行了结构表征. 通过光谱手段比较了两种配合物在不同条件下的反应性. 结果表明，, 在3377 ℃，, pH 22.22时，, 配合物I的分解速率比配合物II慢；|而对于光照射条件下的光化学反应、H22O22存在下的氧化反应、EDTA为配体的取代反应，, 配合物I的分解速率比配合物II快.

Two new chromium(III) complexs [Cr(III)(55-Cl-SA)(en)22]Cl•22CH33OH•22H22O (I) and [Cr(III)(55-Cl-SA)(TETA)]ClO44•H22O (II) (55-Cl-SA=＝55-Cl-salicylic acid, en=＝ethylenediamine, TETA=＝triethylenetetramine) were synthesized and characterized by elemental analysis and X-ray crystallography. The reactivities of those two complexes were compared under different conditions by using UV-Vis and fluorescence spectroscopy. The results indicated that under acid condition, complex II decomposition speed is quicker than complex I|while for the photochemistry reaction, redox reaction in the condition of H22O22 and kinetic activity in the presence of EDTA, the decomposition rate of complex II is slower than complex I.

Key words: chromium complex, 55-Cl-salicylic acid, ethylenediamine, triethylenetetramine, decomposition speed
