摘要
合成了以糠醛水杨酰腙为配体的一个镍配合物Ni(C12H9N2O3)2(C5H5N)2,进行红外光谱和紫外光谱分析,并测定晶体结构.该晶体为深红褐色,属三斜晶系,空间群为P1-,晶胞参数:a=1.02003(4)nm,b=1.11947(6)nm,c=1.48619(9)nm,α=105.960(2)°,β=93.819(2)°,γ=100.457(1)°.晶体结构分析表明,Ni2+具有畸变的八面体配位构型,配位原子分别来自两个二齿配体糠醛水杨酰腙的两个氧原子和两个氮原子以及两个配位吡啶的氮原子.
The mononuclear nickel (II) complex Ni (C_(12)H_9N_2O_3)_2(C_5H_5N)_2 has been prepared by the reaction of Ni(AC)_2 with N-furfural-N'-salicylhydrazone Schiff base ligand and characterized by elemental analysis, IR spectrum, UV-visible spectrum and single crystal X-ray diffraction. The crystal crystallizes in triclinic space group P(1)- with cell parameter a=1.02003(4)nm, b=1.11947(6)nm, c=1.48619(9)nm, α=105.960(2)~°, β=93.819(2)°, γ=100.457(1)° . The crystal structure indicates that the Ni^(2+) has a distorted octahedral geometry, in which the two primary ligands participate in coordination with two O and two N atoms and the secondary ligand takes part in bonding with N donor atom.
