Abstract

The intermetallic compound Zr2Ni has been found to take up hydrogen on charging at room temperature. Zr2(NiFe) H4.7 and Zr2(NiFe) H4.5 show the same structure (CuAl2 type) as the uncharged compound but with an expanded lattice.

Analysis of room temperature spectra in zero and applied fields indicates that the57Fe atoms occupy Ni sites in Zr2(Ni 57Fe). Volume expansion effects account for about one third of the increase in isomer shift (∼ +0.58 mms−1) observed on hydrogenation. The distribution of hydrogen atoms around the probe37Fe atoms also causes a decrease of ∼0.23 mms−1 in the mean value for the quadrupole splitting compared Rith uncharged Zr2Ni.
