High-pressure Raman experiments were performed on Sm2Mo4O15 system up to 7.9 GPa. This system exhibits a irreversible structural amorphization at 5.0 GPa. This structural change in Sm2Mo4O15 has strongly first-order character. The amorphous phase can be originated from the hindrance of a crystalline structural phase transition. Assignment of Raman modes of the ambient-pressure phase of Sm2Mo4O15 was proposed, based on lattice dynamics calculations.
