Hf10MnSb5 crystallizes in the tetragonal I422 space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 6-coordinate geometry to one Mn(1), one Sb(2), and four equivalent Sb(1) atoms. In the second Hf site, Hf(2) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. Mn(1) is bonded in a distorted q6 geometry to eight equivalent Hf(1) and two equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 10-coordinate geometry to two equivalent Hf(2) and eight equivalent Hf(1) atoms. In the second Sb site, Sb(2) is bonded in a distorted q6 geometry to eight equivalent Hf(1) and two equivalent Mn(1) atoms.
