| 摘要: 采用回流法在水溶剂中合成了2个含氮配体单核镍配合物[Ni（phen）2（H2O）2]（1，6-nds）·2H2O（1）和[Ni（phen）3]（1，6-nds）·10H2O（2）（1，6-nds=1，6-萘二磺酸根离子，phen=1，10-邻菲罗啉）。配合物1中，镍离子与2个1，10-邻菲罗啉和2个水分子配位，形成[Ni（phen）2（H2O）2]2+阳离子。2个没有配位的水分子通过氢键与[Ni（phen）2（H2O）2]2+和1，6-萘二磺酸根离子相互连接形成二维层状结构。配合物2中，镍离子与3个1，10-邻菲罗啉配位，形成[Ni（phen）3]2+阳离子。大量的氢键将自由的水分子和1，6-萘二磺酸根离子连接形成三维网状结构。2个配合物中1，6-萘二磺酸根离子均没有与镍离子配位，只是起到平衡电荷的作用。室温下，配合物显示了较大的荧光发射峰，其最大发射峰分别在443和438nm。 |

| Abstract: The synthesis of the two Ni(Ⅱ) mononuclear complexes containing N-donor ligands [Ni(phen)2(H2O)2](1,6-nds)·2H2O (1) and [Ni(phen)3](1,6-nds)·10H2O (2) (1,6-nds=1,6-naphthalene-disulfonate anion, phen=1,10-phenanthroline) was conducted in water by the reflux method. For the complex 1, the nickel ion coordinates with two 1,10-phenanthroline ligands and two water molecules, respectively, forming the [Ni(phen)2(H2O)2]2+ cation, and the two uncoordinated water molecules connect to the [Ni(phen)2(H2O)2]2+ cations and 1,6-nds anions to form a two-dimensional layered structure via the hydrogen bonds. For the complex 2, the nickel ion coordinates with three 1,10-phenanthroline ligands to form the [Ni(phen)3]2+ cation. There are abundant hydrogen bonds between free water molecules and 1,6-nds anions, leading to a three-dimensional network structure. In the two complexes, the 1,6-nds anions don't coordinate with the nickel ions, only balance the charges. The complexes exhibit strong luminescence with emission maximum at 443 and 438 nm at room temperature, respectively. |
