摘要：

The structural transformations in pyridine nitrate PyHNO3 (C5D5NHNO3) are investigated by neutron diffraction in the temperature range 16–300 K at normal pressure and in the high-pressure range 0–3.5 GPa at room temperature. A new high-pressure phase with a monoclinic structure (space group P21/c) is revealed in the PyHNO3 compound at pressures P > Ptr ∼ 1 GPa. The geometry of hydrogen bonds and the coordination of the PyH+ and NO3− ions in the structure of the PyHNO3 compound are studied as a function of the temperature and pressure.
