利用缓慢蒸发溶剂法合成了单核镍(Ⅱ)配合物[Ni(3,5-(SO3)2CatH2)(phen)2(H2O)]·4H2O(CatH2=1,2-二羟基苯,phen=1,10-邻菲罗啉)。利用X-射线单晶衍射、元素分析、红外光谱、热重分析和荧光光谱等对其进行了表征。结果表明,该配合物属于三斜晶系,P1空间群。镍离子与一个1,2-二羟基苯-3,5-二磺酸根离子、两个1,10-邻菲罗啉配体和一个水分子配位,形成[Ni(3,5-(SO3)2CatH2)(phen)2(H2O)]结构。在结构单元中,还有四个未配位的水分子。未配位的水分子和[Ni(3,5-(SO3)2CatH2)(phen)2(H2O)]结构通过O-H…O氢键相连,形成三维网状结构。与配体相比,配合物的荧光发射谱发生红移,发射峰在645 nm。荧光寿命为1.07 ns。
The mononuclear nickel (Ⅱ) complex [Ni (3,5- (SO3) 2CatH2) (phen) 2 (H2O)] 4H2O (CatH2 = 1,2-dihydroxybenzene, phen = 1,10-o-phenanthroline). It was characterized by X-ray single crystal diffraction, elemental analysis, infrared spectroscopy, thermogravimetry and fluorescence spectroscopy. The results show that the complex belongs to triclinic system, space group P1. Nickel ions coordinate with a 1,2-dihydroxybenzene-3,5-disulfonate ion and two 1,10-phenanthroline ligands and a water molecule form [Ni (3,5- (SO3 ) 2CatH2) (phen) 2 (H2O)] structure. In the structural unit, there are four uncoordinated water molecules. Uncoordinated water molecules and [Ni (3,5- (SO3) 2CatH2) (phen) 2 (H2O)] structure are connected by O-H ... O hydrogen bonds to form a three-dimensional network structure. Compared with the ligand, the fluorescence emission spectrum of the complex was redshifted and the emission peak was at 645 nm. Fluorescence lifetime is 1.07 ns.
