摘要
制备了一个结构新颖的镍的二价配合物,并过元素分析,红外光谱和X-射线衍射对其进行表征.结果表明该配合物属三斜晶系,空间群为P-3c1,晶胞晶胞参数为:a=11.9404(8),b=11.9404(8),c=17.087(2),V=2109.8(3)3,Z=4,Dc=1.389 Mg/m3,F(000)=924,化学式C7H26N7N i O1S1,化学式量为317.7.中心镍离子与3个乙二胺的六个氮原子配位成一个变形八面体结构.同时,晶体中含有没有配位的逆硫氰根离子和水分子.配合物结构单元的分子之间是通过氢键相连接,从而形成了比较稳定的一维链状结构.
A novel nickel (Ⅱ) complex incorporating an inorganic anion and three ethylenediamine ligand (Ni (en) 3) × (NCS) has been prepared and structurally characterized by elemental analysis, IR spectra and X- ray diffraction. The Ni( Ⅱ) ion has a distorted octahedron coordination environment with six nitrogen atoms, and there' s an uncoordination isothiocyanato anion and water molecule in the crystal. The complex exhibits a one-dimensional structure via the intra-molecular hydrogen bonding.
