5-bis((bis(2-hydroxylethyl)amino)methyl)-4H-1,2,4,-triazol-4-amine) and benzoate sodium. The X-ray structure shows that complex 1 consists of a cyclic tetranuclear nickel(II) cation and four uncoordinated ClO4– anions and two crystalline water molecules, in which four nickel atoms have distorted octahedral coordination. Magnetic studies indicate the existence of antiferromagnetic coupling between the nickel(II)
通过高氯酸镍 (II) 与 L (L = 3) 反应制备了环状四核 [Ni4(H–1L)2(μ-PhCOO)2(H2O)4](ClO4)4·2H2O (1) 配合物,5-双((双(2-羟乙基)氨基)甲基)-4H-1,2,4,-三唑-4-胺)和苯甲酸钠。X 射线结构显示配合物 1 由一个环状四核镍 (II) 阳离子和四个未配位的 ClO4- 阴离子和两个结晶水分子组成,其中四个镍原子具有扭曲的八面体配位。磁性研究表明镍 (II) 离子之间存在反铁磁耦合。已经通过紫外吸收和荧光光谱研究了复合物与小牛胸腺 DNA (CT-DNA) 的相互作用,此外,DNA 切割实验表明复合物通过氧化机制切割 DNA。
