A new compound, [RbHTNR]∞ [HTNR^-： C6H（NO2）3（OH）O^-], was synthesized by the reaction of rubidium nitrate and styphnic acid. The molecular structure was characterized using X-ray diffraction analysis, elemental analysis and FFIR spectroscopy. The crystalline is monoclinic with space group P21/n and the empirical formula C6H2N3O8Rb. The unit cell parameters are： a=0.4525 nm, b=1.0777 nm, c=1.9834 nm, β=90.47（2）°, V= 0.96725 nm^3, Z=4, Dc =2.263 g/cm^3, Mr=329.58, F（000）= 640,μ（Mo Ka）=5.165 mm^-1. The thermal decomposition mechanism of the complex was studied by differential scanning calorimetry （DSC）, thermogravimetryderivative thermogravimetry （TG-DTG） and FFIR techniques. At the linear rate of 10 ℃/min, the thermal decomposition of the complex showed three mass reducing processes between 60 and 500 ℃, and finally evolved RbCN and some gaseous products.
