New hydrides and deuterides of Laves cubic phases ZrFe2 and ZrCo2 were synthesized by high hydrogen (deuterium) pressure technique. For both Laves phases the symmetry of lattice does not change but a large expansion of lattice parameter (by 8% for ZrFe2 and by 4.5% for ZrCo2) occurs during hydrides (deuterides) formation. In contrast to the rela-tively stable hydride (if stored in an inert atmosphere) formed in ZrFe2, the ZrCo2H2 de-composes easily at 25°C. Large lattice expansion of ZrFe2 during the deuteride formation changes only slightly its magnetic properties.
