Molecular Structure of Low Temperature Form of Triaminoguanidinium Nitrate (TAGN)

A rigid-body motion study of triaminoguanidinium nitrate (TAGN) was initiated originally in order to determine if nitrate ion libration might be responsible for the TAGN fast burning rate. A low temperature polymorph of TAGN was discovered by this laboratory during the course of this rigid-body motion study. Continuation of this libration study in the lower temperature regime, however, necessitated understanding the molecular structure of the low temperature form of TAGN. To do this a signal-crystal x-ray diffraction structure determination of the low temperature form was undertaken. The crystal structure was determined including space group, lattice parameters, atomic coordinates and temperature factors, hydrogen bonding, and density.
