Rodriguez, Mark; Campana, Charles; Rae, A David; Graeber, Edward; Morosin, Bruno


The crystal structure of form III of the title compound, HNAB [systematic name: bis(2,4,6-trinitrophenyl)diazene], C12H4N 8O12, has finally been solved as a pseudo-merohedral twin (monoclinic space group P21, rather than the orthorhombic space group C2221 suggested by diffraction symmetry) using a dual space recycling method. The significant differences in the room-temperature densities of the three crystalline forms allow examination of molecular differences due to packing arrangements. An...[Show more]
