Studies of Phase Transitions of Chromium Coordination Compounds under High Pressure

In this paper, the high pressure Raman scattering spectroscopy of Cd2(HATr)4(NO3)4·H2O (Cd) was measured by diamond anvil cells (DACs) up to 10GPa. The Raman spectra of Cd at 0GPa was assigned completely. With pressure increased to 6GPa, a new Raman peak appeared and the original C-NH2 bending vibration mode and N-NH2 bending vibration mode disappeared, indicating that Cd underwent a phase transition
