Ni16Mn6Ge7 crystallizes in the cubic Fm-3m space group. Mn(1) is bonded in a 16-coordinate geometry to four equivalent Mn(1), four equivalent Ni(1), four equivalent Ni(2), and four equivalent Ge(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(2) is bonded in a 6-coordinate geometry to three equivalent Mn(1) and three equivalent Ge(2) atoms. In the second Ni site, Ni(1) is bonded in a 4-coordinate geometry to three equivalent Mn(1), one Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Mn(1), four equivalent Ni(1), and four equivalent Ni(2) atoms. In the second Ge site, Ge(1) is bonded in a body-centered cubic geometry to eight equivalent Ni(1) atoms.
