以反丁烯二酸和咪唑为原料,采用缓慢蒸发溶剂法合成了新的有机加合物C14H14N4O8,并获得了其单晶体.通过红外、热化学分析、X-射线单晶衍射等技术对该加合物进行了结构测定和性质表征.晶体中分子通过分子间氢键相互连接构成超分子网络结构.该加合物属于三斜晶系,P-1空间群,a=0.746 77(15),b=7.736 3(15),c=8.405 5(17),α=69.73(3)°,β=80.40(3)°,γ=66.19(3)°,Z=1,V=416.75(14)3,D=1.468(mg/m3),F(000)=190.
A new organic adduct, C14H14N4O8, was synthesized by slow evaporation solvent method using fumaric acid and imidazole as raw materials, and its single crystal was obtained.It was obtained by infrared, thermochemical analysis and X-ray single crystal diffraction The structures of the complexes are characterized by their structure and properties. The molecules in the crystal are interconnected by intermolecular hydrogen bonds to form a supramolecular network structure. The adduct belongs to the triclinic system, P-1 space group, a = 0.746 77 (15), α = 69.73 (3) °, β = 80.40 (3) °, γ = 66.19 (3) °, Z = 1, V = 416.75 (14) 3, D = 1.468 (mg / m3), F (000) = 190.
