摘要
A cobalt(II) complex, [CoLCl](2)[CoLCl0.5(H2O)(0.5)]2ClO(4)center dot 10H(2)O (1) (LH=(2-(bis((1H-benzo[d]-imidazol-2-yl) methyl)amino)acetic acid)) has been synthesized and characterized. Its catecholase catalytic activity has been exploited by UV-Vis spectrophotometric study by using 3,5-di-tert-butylcatechol (3,5-DTBC) as the substrate. The results showed that two cobalt(II) ions of the asymmetric unit were both coordinated by the ligands in a distorted trigonal-bipyramidal geometry in the crystal structure. Complex 1 exhibited pH value dependence for the oxidation of 3,5-DTBC in the range of pH 5 to 11, and its catecholase catalytic activity increased with increasing temperature. The kinetics of oxidation of 3,5-DTBC catalyzed by complex 1 accorded with the Michaelis-Mentent equation.
