The crystal structure of four saturated deuterides of oxygen-modified intermetallic compounds Ti_4–xZr_xFe₂O_y (x = 1, 2, 3; y = 0.25, 0.5) has been investigated by both X-ray and neutron powder diffraction. The distribution of D-atoms in the metal matrix has been determined and analysed as function of the Ti/Zr and oxygen content. The obtained crystallographic data were compared with structural results for other oxygen-stabilised Ti/Zr-based h-phases.
