摘要：
A new macrocyclic dinuclear Zn(II) complex, [Zn-2(OAc)L]center dot ClO4 (H2L was obtained by condensation between 3,3'-(ethane-1,2-diylbis(benzylazanediyl))bis(methylene)bis(2-hydroxy-5-methylbenzaldehyde) and aniline (1 : 2 molar ratio)), was synthesized and characterized by spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The interactions of the complex with DNA have been measured by UV spectroscopy and viscosity experiment. The interaction of the complex with calf thymus DNA has a binding constant of 1.18 x 10(4) mol(-1) L. Phosphate hydrolysis of the complex was investigated using bis(4-nitrophenyl) phosphate as the substrate. The observed first-order rate constant is 4.23 x 10(-5) s(-1).
