Hf Hf Al Ga
HfGaHfAl is alpha oxygen-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one aluminium--hafnium (1/1) molecule and one HfGa cluster. In the HfGa cluster, Hf(2) is bonded in a single-bond geometry to one Ga(1) atom. The Hf(2)-Ga(1) bond length is 0.60 Å. Ga(1) is bonded in a single-bond geometry to one Hf(2) atom.
