ResumoThe structural properties of LaNi4CoD6.11 and LaNi3.55Mn0.4Al0.3Co0.75D5.57 deuterides have been investigated by means of powder neutron diffraction analysis. The data analysis of LaNi4CoD6.11 deuteride has been performed using a modified Rietveld procedure in order to take into account the anisotropic broadening of the observed diffraction lines. Distribution of Mn, Al and Co substituting atoms on the nickel sublattice and occupancy rate determination of the occupied deuterium sites have been achieved and are compared with those of other single substituted compounds.
