Presence of molecules in a crystal structure produces structural and electronic anisotropy. Such anisotropy can be a cause to yield various novel high-pressure phenomena in molecular crystals. They include pressure-induced metallization, amorphization and recrystallization, molecular formation/dissociation, superconductivity and amorphous-amorphous transition. This report reviews high-pressure behavior of molecular crystal SnI4 which does show those phenomena.
