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
