The compound described by HfGa crystallizes in the orthorhombic Pbcm space group. There are three inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 6-coordinate geometry to two equivalent Ga(3) and four equivalent Ga(2) atoms. In the second Hf site, Hf(2) is bonded in a 9-coordinate geometry to one Ga(2), four equivalent Ga(1), and four equivalent Ga(3) atoms. In the third Hf site, Hf(3) is bonded to one Ga(3), two equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of distorted corner, face, and edge-sharing HfGa7 pentagonal bipyramids. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to two equivalent Hf(3), four equivalent Hf(2), two equivalent Ga(1), and two equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to one Hf(2), four equivalent Hf(1), and four equivalent Hf(3) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to one Hf(3), two equivalent Hf(1), four equivalent Hf(2), and two equivalent Ga(1) atoms. is represented by the CIF file [CIF]
