Abstract
The copper-red hydride SrPdH2.7 has been obtained by heating an Sr-Pd alloy at 200-degrees-C under a hydrogen atmosphere. The alloy was prep ared from fusing equimolar amounts of the individual metals. X-ray and neutron diffraction experiments led to the perovskite-type structure in which the hydrogen atoms statistically occupy the threefold site wi th an occupancy factor of 0.91(4). Correlations between the volume inc rements of the hydrogen atoms and the bonding properties will be discu ssed for SrPdH2.7 and structurally related hydrides.
