Abstract : An x-ray diffraction single-crystal structure determination of Bis(2, 2-dinitropropyl)-nitramine (BDNPN) was carried out. Bis(2, 2-dinitropropyl)-nitramine has the molecular formula C6H10N6O10 and a density of 1.78 g/cc. It crystallizes with two formula weights in the C-centered monoclinic space group C2 (no. 5) with unit cell parameters a = 10.726(4) A, b = 5.992(3) A, c = 10.400(4) A, and beta = 110.01(3) deg. The positions of the atoms were determined with both direct methods and difference Fourier techniques. The structure was refined to a final R value of 0.036. The crystal structure consists of BDNPN molecules oriented along the c axis at 000 and 220. The crystal is held together by van der Waals forces between each molecule and its six nearest-neighbors. The molecule is composed of two gem-dinitropropyl groups bonded to a central nitramine group. A comparison of the thermochemical data of BDNPN, cyclotrimethylenetrinitramine (RDX), and 1, 3, 3-trinitroazetidine (TNAZ) reveals that BDNPN has the highest Impetus and lowest flame temperature within this group of molecules.
