A new intermetallic deuteride Ce{sub 2}Ni{sub 7}D{sub 4.7} with an anomalous volume expansion has been studied. Its structure was solved on the basis of in situ neutron diffraction data. Expansion proceeds along the c-axis and within the CeNi{sub 2} slabs only. All D atoms are located inside these s...
