【摘要】 以磺胺对甲氧基嘧啶（H-L）为配体,合成了一个新的钴配合物[Co（L）₂（H₂O）₂]·2CH₃OH。采用元素分析、红外光谱、质谱和X-射线单晶衍射进行结构表征。配合物属于单斜晶系,空间群为P2₁/c,中心金属钴与来自两个磺胺对甲氧基嘧啶的磺酰胺氮、嘧啶氮及两个水分子形成六配位八面体稍变形的配位构型。粘度和电泳实验表明,配合物与DNA具有一定的插入作用。更多还原

【Abstract】 A new Co（Ⅱ） complex,[Co（L）₂（H₂O）₂]·2CH₃OH（H-L=4-amino-N-（5-methoxy-2-pyrmidiny） benzenesulfonamide）,was synthesized and fully confirmed by elemental analysis,IR,MS and single crystal X-ray diffraction analysis.The results show that the complex in a monoclinicsystem with space group P2₁/c.The Co（Ⅱ） is six-coordinated by two L via two sulfonamide N atoms,two pyridazine N atoms,as well as two O atoms from two water,forming a slightly distorted octahedral geometry.The viscosity measurement and gel electrophoresis test indicated that the complex can bind with DNA by intercalative binding mode.更多还原
