The material structure described by Hf2Ga3 crystallizes in the orthorhombic Fdd2 space group. Hf(1) is bonded in a 9-coordinate geometry to three equivalent Ga(1) and six equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to six equivalent Hf(1) and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to six equivalent Hf(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. is represented by the CIF card [CIF]
