Figure 4
Crystal structures of (left) NdGa and (middle to right) its hydride phases NdGaH1.6−x (x < 0.5), NdGaHy (1 < y < 1.15) and NdGaHy (y < 1), respectively. Nd and Ga atoms are depicted as gray and red circles, respectively. H atoms and their metal coordination polyhedra are represented in green (trigonal–bipyramidal interstitial) and teal (tetrahedral interstitial). Light green indicates partial occupancy. Formation conditions for the hydride phases are indicated as arrows.
