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 mononuclear Mn (Ⅱ) complex [Mn (phen) 2 (H2O) 2] · (H2O) 6 · SO4 (phen = 1,10-phenanthroline was synthesized by the method of slowly evaporating the solvent. ). Its structure and composition were confirmed by single crystal X-ray diffraction and elemental analysis. The complex belongs to triclinic system with space group P-1. The central ion of this complex is Mn (II). The central ion coordinates with two 1,10-phenanthroline and two water molecules. There are six uncoordinated water molecules in the unit cell and a free Sulfate ion. There are a variety of structural hydrogen bonds in the complex, including planar triangles, tetrahedrons, tetragons, pentagons and hexagons.
