The structure described by Hf3In4 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 10-coordinate geometry to two equivalent Hf(1), four equivalent Hf(2), and four equivalent In(1) atoms. In the second Hf site, Hf(2) is bonded to two equivalent Hf(1), two equivalent Hf(2), and eight equivalent In(1) atoms to form a mixture of distorted edge, face, and corner-sharing HfHf4In8 cuboctahedra. In(1) is bonded in a 5-coordinate geometry to one Hf(1) and four equivalent Hf(2) atoms. is represented by the CIF file [CIF]
