class="label">•: YMn_2−xFe_x(H,D)_y compounds (5 ≤ y ≤ 6) were synthesized under high H or D pressure.
class="label">•: Their structural and magnetic phase diagrams were determined versus Fe content.
class="label">•: They form complex hydrides with YMn₂H₆ type structure for x < 1.
class="label">•: They form interstitial hydrides with cubic or orthorhombic structures for x > 0.2.
class="label">•: A large H/D isotope effect is observed on interstitial compound cell volumes.
