摘要：

Crystals of C(NH2)3+.NO3- are built of sheets of guanidinium and nitrate ions linked by N-H...O hydrogen bonds of length 2.945 (6), 2.962 (8) and 2.968 (6) angstrom. The sheets are perpendicular to the crystallographic mirror planes; the C and N(1) atoms of the guanidinium cations, and the N and O(1) atoms of the nitrate anions, lie on these planes. It appears that pronounced changes of the crystal shape, observed at the first-order phase transition of guanidinium nitrate crystals at 296 K, are connected with shear shifts of the sheets in the crystal lattice.
