多水体系单核Mn(Ⅱ)配合物的合成、晶体结构和氢键研究

Study on the Synthesis, Crystal Structure and Hydrogen Bond of Mn(Ⅱ)Mononuclear Complex Containing Multi-water Molecules

采用缓慢蒸发溶剂的方法,在去离子水中合成了单核Mn(Ⅱ)配合物[Mn(phen)2(H2O)2]·(H2O)6·SO4(phen=1,10-邻菲罗啉)。利用X射线单晶衍射和元素分析等表征手段确定了其结构和组成。该配合物属于三斜晶系,空间群为P-1。该配合物的中心离子为Mn(Ⅱ),中心离子与两个1,10-邻菲罗啉和两个水分子配位,在晶胞中还有六个未配位的水分子和一个自由的硫酸根离子。配合物中存在多种结构的氢键,包括平面三角形、四面体形、四边形、五边形和六边形。

The Mn（ II ） mononuclear complex [Mn（phen）2（H2O）2]·（H2O）6·SO4 （phen=1,10-phenanthroline） was synthesized in deionized water by slow evaporation of the solvent. The structure and composition were characterized by X-ray crystal diffraction and elemental analysis, etc. The crystal of the complex can crystallize in triclinic system with a space group of P-1. The complex central ion is Mn （II）, it coordinates with two 1,10- phenanthroline and two water molecules. In the unit, there are six un-coordinating water molecules and a free sulfate ion. There are many hydrogen bonds with various structures, including plane triangle, tetrahedron, quadrangle, pentagon and hexagon.
