Abstract: 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 P1.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. |
