摘　　要：The new complex, [K2(TNR)(H2O)]n, was prepared by reacting 2,4,6 trinitroresorcinol with potassium hyd roxide. Its crystal structure was determined by X ray single crystal diffraction analysis. The crystalline belongs to triclinic with space group .Its unit cell parameters are as follows:a=0.6993(1)nm, b=0.9474(2)nm, c=0.9791(1)nm, α=115.28(1)°, β=107.86(1)°, γ=95.94(1)°, V=0.53717(15)nm3, Z=2, Dc=2.098g ·cm-3, F(000)=340. The two potassium ions have different coordination numbers of which are 8 and 9, respectively. The thermal decomposition mechanism of the complex was studied by using DSC, TG GTG and FT IR techniques. The existence of KNC in the residue is shown in FT IR.
