HfV2Ga4 crystallizes in the tetragonal I4/mmm space group. Hf(1) is bonded in a distorted square co-planar geometry to twelve Ga(1,1) atoms. V(1) is bonded in a 10-coordinate geometry to two equivalent V(1) and eight Ga(1,1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Hf(1); four equivalent V(1); and four Ga(1,1) atoms. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Hf(1), four equivalent V(1), and four equivalent Ga(1) atoms.
HfV2Ga4 crystallizes in the tetragonal I4/mmm space group. Hf(1) is bonded in a distorted square co-planar geometry to twelve Ga(1,1) atoms. There are four shorter (2.74 Å) and eight longer (3.13 Å) Hf(1)-Ga(1,1) bond lengths. V(1) is bonded in a 10-coordinate geometry to two equivalent V(1) and eight Ga(1,1) atoms. Both V(1)-V(1) bond lengths are 2.58 Å. All V(1)-Ga(1,1) bond lengths are 2.65 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Hf(1); four equivalent V(1); and four Ga(1,1) atoms. There are two shorter (2.52 Å) and two longer (2.75 Å) Ga(1)-Ga(1,1) bond lengths. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Hf(1), four equivalent V(1), and four equivalent Ga(1) atoms.
