摘要

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 FTIR spectroscopy. The crystalline is monoclinic with space group P21/n and the empirical formula C6H2N3OsRb. The unit cell parameters are: a=0.4525 nm, b=1.0777 nm, c= 1.9834 nm, β=90.47(2)°, V=0.96725 nm3, Z=4, Dc=2.263 g/cm3, Mr=329.58, F(000)=640, μ(Mo Kα)=5.165 mm-1. The thermal decomposition mechanism of the complex was studied by differential scanning calorimetry (DSC), thermogravimetryderivative thermogravimetry (TG-DTG) and FTIR 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.
