We performed high-pressure and high-temperature X-ray diffraction experiments on InOOH using laser heated diamond anvil cells. After heating at i300 K, pyrite-type InOOH was formed at 14 GPa and it was stable up to at least 30 GPa. Pyrite-type InOOH partially transformed back to distorted rutile-type InOOH after recovery. The lattice constant and unit-cell volume of pyrite-type InOOH were determined to be a0 = 5.3151(8) Å and V0 = 150.15 (7) Å3 at ambient conditions, respectively. The density difference between pyrite-type and distorted rutile-type InOOH was 5% at ambient condition.
