摘要
利用4-氨基-1,2,4-三唑与苦味酸的甲醇溶液制备了4-氨基-1,2,4-三唑苦味酸盐,并于室温下培养出单晶。通过X射线单晶结构分析法测定其晶体结构,晶体属于正交晶系,空间群为Pbcn,晶胞参数为:a=0.9207(3)nm,b=1.9874(6)nm,c=1.3304(4)nm,β=90°,V=2.434(5)nm3,Dc=1.709g/cm3,Z=8,F(000)=1280,R1=0.0584,wR2=0.1840。运用DSC测得配合物在298.15K时的标准摩尔比热容为484.39J/(mol.K),比热容与温度的关系式为:Cp(J/(g.K))=0.4435+3.6997×10-3T。
The titled complex was prepared with 4-amino-1,2,4-triazole and picric acid in methanol.Single crystals were grown at room temperature.The crystal belongs to orthorhombic system,space group Pbcn with crystal parameters of a = 0.9207(3) nm,b = 1.9874(6) nm,c = 1.3304(4) nm,β = 90°,V = 2.434(5) nm^3,Dc = 1.709g /cm3,Z = 8,F(000) = 1280,R1 = 0.0584,wR2 = 0.1840.The standard molar specific heat capacity measured in 298.15 K by DSC was 484.39 J.mol-1.K-1.The relationship between the specific heat capacity of the complex and temperature was Cp(J.g^-1.K^-1) = 0.4434523 + 3.699795 × 10^-3 T.
