?Synthesis,Crystal Structure and Thermal Stability of Co(II),Ni(II) Complexes with Benzylidene Acetone Salicylhydrazone

摘要:

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)，通过FTIR、热分析、X-射线单晶衍射和X-射线粉末衍射等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a=1.0347(3)nm，b=1.0052(4)nm，c=1.4541(4)nm；α=92.830(4)?，β=109.054(3)?，γ=96.091(4)?，V=1.9792(10) nm3，Z=2，F(000) =814，R1=0.0506。配合物2属于P-1空间群，晶胞参数a=1.0435(5)nm，b=1.3940(7)nm，c=1.4542(7)nm；α=92.41(2)?，β=109.73(2)?，γ=95.80(2)?，V=1.9745(17) nm3，Z=2，F(000) =816，R1=0.0438。热失重分析表明，配合物1、2的晶体结构在低于200℃的温度下是稳定的。

Abstract:

Two complexes,Co(LPy)2(1) and Ni(LPy)2(2) were synthesized from the reaction of Benzylidene Acetone Salicylhydrazone (HL) with Co(NO3)2, Ni(NO3)2,and characterized by FTIR,thermal analysis,single crystal X-ray diffrac-tion and XRD.The results of structuralanalysis indicate that both complexes aredistorted octahedral.Complex 1 belongs to triclinic system,space group P-1 witha=1.0347(3)nm,b=1.0052(4)nm,c=1.4541(4)nm;α=92.830(4)?β=109.054(3)?γ= 96.091(4)?V=1.9792(10)nm3,Z=2,F(000) =814,R1=0.0506.Complex 2 belongs to triclinic system,space group P-1 with a=1.0435(5)nm,b=1.3940(7)nm,c=1.4542(7)nm;α=92.41(2)?β=109.73(2)?γ=95.80(2)?V=1.9745(17)nm3,Z=2,F(000) =816,R1=0.0438.The result of TG analysis shows that the title complexswere stable under 200 ℃.
