From: New high-pressure van der Waals compound Kr(H2)4 discovered in the krypton-hydrogen binary system
Compressional behaviour of the Kr(H2)4 structure.
(a) Pressure-volume data. A Vinet equation of state (EoS) fitted to the data with V0 = 5237.952 Å3 gives B0 = 0.18(3) GPa and B′ = 7.7(2). The fixed V0 value is based on the equivalent volumes of pure, solid krypton and hydrogen. (b) Intra- and shortest inter-octahedral Kr-Kr distances as function of pressure. For comparison Kr-Kr distances in the pure krypton solid (16) are given in the inset. Solid lines are guides to the eye.
