Abstract : The crystal structure of trifluoroethyl tetryl (N-(beta,beta,beta-trifluoroethyl)-N,2,4,6-tetranitroaniline) has been determined by X-ray diffraction. The unit cell is orthorhombic (a = 12.01, b = 11.87, c = 9.41 A), space group Pna21 with four molecules per cell. The nitramine group is rotated 86 deg out of the plane of the benzene ring and the 2-,4- and 6-nitro groups are rotated 19 deg, 12 deg and 39 deg respectively. The non-coplanarity of the 4-nitro group is due to intermolecular crowding but the other groups are configured to avoid both short intermolecular and short intramolecular distances between oxygen and fluorine atoms.
