采用亚苄基丙酮水杨酰腙配体(HL)分别与Co(NO3)2、Ni(NO3)2溶液进行反应,得到两个配合物Co(LPy)2(1)、Ni(LPy)2(2),并通过FTIR、热分析、X射线单晶衍射和X射线粉末衍射手段对其进行了表征。X射线单晶衍射结果表明,两个配合物均为扭曲四角双锥构型,属三斜晶系。配合物1属于P-1空间群,晶胞参数为a=1.034 7(3)nm,b=1.405 2(4)nm,c=1.454 1(4)nm;α=92.830(4)°,β=109.054(3)°,γ=96.091(4)°,V=1.979 2(10)nm3,Z=2,F(000)=814,R1=0.050 6。配合物2属于P-1空间群,晶胞参数为a=1.043 5(5)nm,b=1.394 0(7)nm,c=1.454 2(7)nm;α=92.41(2)°,β=109.73(2)°,γ=95.80(2)°,V=1.974 5(17)nm3,Z=2,F(000)=816,R1=0.043 8。热失重分析表明,配合物1、2的晶体结构在低于200℃下是稳定的。
The complex of Co (LPy) 2 (1), Ni (LPy) 2 (2) was obtained by the reaction of benzylidene acetonide salicyloyl hydrazone ligand (HL) with Co (NO3) 2 and Ni (NO3) ), And characterized by FTIR, thermal analysis, X-ray single crystal diffraction and X-ray powder diffraction. X-ray single crystal diffraction results show that the two complexes are twisted quadrangular conical configuration, is a triclinic. Complex 1 belongs to the P-1 space group. The unit cell parameters are a = 1.034 7 (3) nm, b = 1.405 2 (4) nm, c = 1.454 1 = 109.054 (3) °, γ = 96.091 (4) °, V = 1.979 2 (10) nm3, Z = 2, F (000) = 814 and R1 = 0.050 6. The complex 2 belongs to the P-1 space group. The unit cell parameters are a = 1.043 5 (5) nm, b = 1.394 0 (7) nm, c = 1.454 2 = 109.73 (2) °, γ = 95.80 (2) °, V = 1.974 5 (17) nm3, Z = 2, F (000) = 816, R1 = 0.043 8. Thermogravimetric analysis shows that the crystal structure of complexes 1, 2 is stable below 200 ℃.
