A new compound (CHZ)(HTNPG).0.5H2O was synthesized by mixing carbohydrazide(CHZ) and trinitrophloroglucinol(TNPG) and characterized by elemental analysis and Fourier transform infrared (FTIR) spectrum.Its crystal structure was determined by single crystal X-ray diffraction analysis.The crystal belongs to triclinic system,P1 space group,with a=0.45578(9) nm,b=1.0142(2) nm,c=1.3041(3) nm,a=86.53(3)°,β=99.56(3)°,γ=81.94(3)°,V=0.5958(2) nm3,Z=2,Dc=2.008 g/cm3,R1=0.0476,and wR2=O.1139.The compound is a di-substituted salt of TNPG,which consists of a cation (CHZ)2+ and an anion (HTNPG)2-.The thermal analysis of the compound was studied by means of differential scanning calorimetry(DSC) and thermogravimetry-derivative thermogravimetry(TG-DTG).Under nitrogen atmosphere at a heating rate of 10 ℃/min,the thermal decomposition of the compound contained one endothermic process of dehydrating stage and two intense exothermic decomposition processes in a temperature range of 140--232℃ on the DSC trace.The decomposition products of the title compound are nearly gaseous products.The existing complicated hydrogen bond networks and electrostatic attraction between (CHZ)2+ and (HTNPG)2-enhance the thermal stability of the title compound.
