Hydrogenation of UFeGe transforms the monoclinic type of structure into the orthorhombic (TiNiSi-type) and subsequently to the hexagonal (ZrBeSi-type) structure. It does not induce magnetic order, however magnetic susceptibility is enhanced. The Sommerfeld coefficient γ increases from 12mJ/molK2 in UFeGe to 36mJ/molK2 in UFeGeH1.7–1.8 (β-hydride). The observed variations of electronic properties are mainly due to the modified geometry of the lattice, characterized by enhanced inter-uranium spacing, and reduced 5f–3d hybridization in the hydrides.
