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438 nm。
Two nitrogen-containing ligand mononuclear nickel complexes [Ni (phen) 2 (H2O) 2] (1,6-nds) · 2H2O (1) and [Ni ] (1,6-nds) · 10H2O (2) (1,6-nds = 1,6-naphthalenedisulfonate ion, phen = 1,10-phenanthroline). In complex 1, nickel ions coordinated with two 1,10-phenanthroline and two water molecules to form [Ni (phen) 2 (H2O) 2] 2+ cation. Two uncoordinated water molecules are connected to each other by hydrogen bonds with [Ni (phen) 2 (H2O) 2] 2+ and 1,6-naphthalenedisulfonate ions to form a two-dimensional layered structure. In complex 2, nickel ion coordinated with 3 1,10-phenanthroline to form [Ni (phen) 3] 2+ cation. A large number of hydrogen bonds will be free water molecules and 1,6-naphthalene disulfonate ions connected to form a three-dimensional network structure. In the two complexes, none of the 1,6-naphthalenedisulfonate ions coordinated with nickel ions, but played a role of balancing the charge. At room temperature, the complex showed a larger fluorescence emission peak with the maximum emission peak at 443 and 438 nm, respectively.
