N，N′-苄基-1，2二胺合铜的合成和晶体结构及与DNA的相互作用

A ligand， (N，N′-dibenzylethane-1，2-diamine) (L)， and its complex with copper acetate was synthesized and characterized by some spectral analyses. The copper(Ⅱ) ion is six-coordinated and exhibites octahedral coordination geometry， the coordination atoms are four nitrogen atoms from two(L) ligands and two carboxyl oxygen atoms from two acetic acid groups， respectively. After studying the interaction of the complex with calf thymus DNA through UV and fluorescence spectra， we can find that there is a strong binding and a large affinity berween the complex and calf thymus DNA.
