The effect of pressure on the crystal structure and lattice parameter of VH..,and NbH ..7 . has been investigated at room temperature by using a diamond-anvil cell up to the pressure of 60 GPa.It was found that the volume increase due to hydrogen, Av,3, is practically in-compressible, and that NbH..., transforms at about 20 GPa into a bct structureisomorphous with /7-VHg .5 .The invariance of Avg under pressure is examined in the more general contextof the apparent invariance of Av. in any host metals, and a tentative explanationfor it in terms of local electronic states is proposed.
