1,3,5,7-TETRAAMMONIUM ADAMANTYL TETRANITRATE (TAATN) CRYSTAL-STRUCTURE

Tetraammonium adamantyl tetranitrate (TAATN) crystallizes in the tetra gonal space group P42(1)cBAR with a = 10.046(1), c = 8.980(2)angstrom, and Z = 2. The positions of the heavy atoms were determined with dire ct methods and the hydrogen atoms were located with difference Fourier methods. The structure was refined to a final R value of 0.038. Each tetravalent tetraammonium adamantyl cation is surrounded by twelve hyd rogen-bonded nearest-neighbor nitrate anions while each anion in turn is surrounded by three nearest-neighbor tetravalent cations.
