We have studied the phase transformation behavior of the potential hydrogen storage compound litium amidoborane at low temperature (from room temperature down to 90 K) and high pressure (from ambient pressure to 9.5 GPa at room temperature and up to 14.7 GPa at 90 K) region using diamond anvil cell. The phase transition phenomenon is characterized by the in situ Raman spectroscopy. The phase transition is evidenced by the splitting of the peak and/or the appearance of new peak in the Raman spectra as well as by the change of the pressure coefficient of the Raman modes. The phase boundary among these phases is also established from the data collected during different cooling cycles. This result provides information about the stability of the bonding characteristics of this potential hydrogen storage material at low temperature and high pressure region.
