含吡唑啉酮酰肼类衍生物的合成与结构

报道了PMBP-NTH(NTH为烟酰肼)与PMBP-PAH(PAH为对甲氧基苯甲酰肼)的合成、表征和晶体结构分析，PMBP-NTH晶体属三斜晶系，具有P1空间群，a=0.9024(2)nm,b=1.0953(2)nm,c=1.1635(2)nm,α67.070(10)°,β=68.220(10)°,γ=84.770(10)°,V=0.9816(3)nm^3,Z=2,Dc=1.345g/cm^3,μ=0.090mm^-1,F(000)=416,R=0.0363,ωR=0.0870.PMBP-PAH属单斜晶系,具有P21/c空间群,a=1.2715(4)nm,b=0.91710(10)nm,c=1.8979(3)nm,β=106.890(10)°,V=2.1177(8)nm^3,Z=4,Dc=1.338g/cm^3,μ=0.090mm^-1,F(000)=896,R=0.0414,ωR=0.0972.这两个化合物在分子内都形成了大的共轭体系,由于分子间氢键力的作用,又使它们在晶体中以二聚体形式存在.
