摘要
合成了一种新的磺酸配合物[Ni(H2O)6](1,5-NDS)(1,5-NDS2-=1,5-萘二磺酸),并对其进行了元素分析和单晶X射线的表征.结果表明,配合物晶体属单斜晶系,空间群为P2(1)/c,晶胞参数为α=1.3239(3)nm,b=0.66463(1)nm,c=0.961 03(2)nm,β=92.00(3)°.V=0.845 1(3)nm3,Z=1,最终R=0.023 8,wR=0.060 3.配阳离子中每个镍原子与6个水分子配位形成八面体构型,其阴离子为1,5-萘二磺酸根,并且阴阳离子通过静电吸引和氢键作用构筑了网络结构.
A novel sulfonate nickel complex [Ni (H2O) 6] (1, 5-NDS) (1, 5-NDS2- = 1, 5 - naphthalenedisulfonate dianion) was synthesized and characterized by elemental analysis and single crystal X-ray diffraction. The title complex belongs to monoclinic system with space group P2(1)/c, a= 1.3239(3)nm, 6 = 0.66463(1)nm, c = 0.961 03(2)nm, β= 92.00(3)°, V=0.8451(3)nm3, Z=1, R = 0.0238, wR = 0.0603. The Ni(Ⅱ) atom resided in the inversion center is coordinated by six water molecules, having a nearly ideal octahedron geometry, with no coordination to the sulfonate groups. Furtherore, a regular framework is formed through electrostatic interactions and the O -H...O hydrogen bonds linking anionic and cationic moieties.
