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(H_2O)_2]·2CH_3OH。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P2_1/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。 A new cobalt complex [Co (L) _2 (H_2O) _2] · 2CH_3OH was synthesized using sulfonamido p-methoxypyrimidine (H-L) as ligand. Structural characterization was performed using elemental analysis, infrared spectroscopy, mass spectrometry and X-ray single crystal diffraction. The complex belongs to the monoclinic system with a space group of P2_1 / c. The center metal cobalt forms a slightly distorted hexacoordination octahedron with sulfonamide nitrogen, pyrimidine nitrogen and two water molecules from two sulfonamido-p-methoxypyrimidines Bit configuration. Viscosity and electrophoresis experiments show that the complexes have some insertion effects with DNA.
