A new energetic organic potassium salt bis(dinitromethyl)difurazanyl ether potassium salt [K2(BDFE)] was synthesized, and structurally characterized by elemental analysis, IR spectra, 13 C NMR and single-crystal X-ray diffraction. K2(BDFE) crystallizes in monoclinic system, space group C2/c with a = 17.342(3), b = 12.6943(17), c = 8.0972(11), β = 110.630(2)°, V = 1668.3(4)3, Z = 4, Dc = 2.000 g/cm3, F(000) = 1000, μ = 0.675 mm-1, S = 1.058, the final R = 0.0499 and wR = 0.1452. The K ion is eight-coordinated with eight O atoms from one water molecule and four bis(dinitromethyl)difurazanyl ethers(BDFE), forming a distorted dodecahedral structure. Thermal decomposition of the title complex was studied by using DSC and TG-DTG. There are primarily two exothermic decomposition processes between 200 and 370 ℃.
