Iridium trihydride (IrH3) is a chemical compound of
GPa.[1]
The bulk modulus of iridium trihydride is 190 GPa which is much less than that of iridium (383 GPa).
Decomposition of iridium trihydride is slow when the pressure is reduced to 6 GPa, and perhaps it can be
metastable
at atmospheric pressures.
A dihydride, IrH2, is predicted to be stable over 14 GPa.[2]
