Synthesis,Crystal Structure and Thermal Analysis of(TAGH)2(TNR)

A new energetic compound(TAGH)2(TNR)(TAG:triaminoguanidine，TNR：2，4，6-trinitromsorcinol) was prepared by reacting triaminoguanidine with 2,4，6-trinitroresoreinol (styphnic acid) in aqueous solution under nitrogen atmosphere,and characterized by elemental analysis and Fourier transform infrared(FTIR)spectra．Its crystal structure was determined by single crystal X-ray diffraction analysis．The crystal belonged to a monoclinic，C2/c space group．The unit cell parameters were as follows：a=2.2892(6)nm,b=1．2802(3)nm,c=1．3661(4)nm，β=111．174(5)°，V=3．7333(16)nm3,and Z=8．The compound consisted of two cations C(N2H3)3+ and an anion(C6HN3O8)2-．The C(N2H3)3+ and (C6HN3O8)2- were bonded together by electrostatic attraction and hydrogen bonds．and this effect made the compound more stable．The thermal analysis of the compound was studied by using differential scanning calorimetry(DSC)，thermogravimetry-derivative thermogravimetry(TG-DTG)．Under nitrogen atmosphere with a heating rate of 10 K·min-1，the thermal decomposition of the compound contained only one intense exothermic decomposition process in the range of 450.1-477.7K in the DSC curve，and the decomposition products were nearly gaseous products．
