中文摘要：
解析了2，9-二(n—2’，5’—二氮杂庚基)—1，10—菲罗啉镍(Ⅱ)配合物的晶体结构，晶体属于单斜晶系，空间群为P2(1)/n，a=1．2510(4)nm，b=1．3501(5)nm，c=1．6849(5)nm，β=106．567(6)°，V=2．7277(16)nm^3，Z=4，镍(Ⅱ)离子与配体的六个氮原子同时配位，形成变形八面体构型，ClO4^-离子的氧原子与邻近的仲胺氮原子上的氢原子之间存在分子间氢键作用．用紫外—可见分光光度计研究了其与DNA的相互使用，采用改进的邻苯三酚自氧化法研究了其对超氧阴离子自由基O2^-.的抑制作用，结果表明该配合物能以插入模式与DNA发生作用，并能有效地抑制超氧阴离子自由基O2^-.的生成．
