Sc6Ni16Ge7 crystallizes in the cubic Fm-3m space group. Sc(1) is bonded in a 12-coordinate geometry to four equivalent Ni(1), four equivalent Ni(2), and four equivalent Ge(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 13-coordinate geometry to three equivalent Sc(1), three equivalent Ni(1), three equivalent Ni(2), one Ge(2), and three equivalent Ge(1) atoms. In the second Ni site, Ni(2) is bonded in a 12-coordinate geometry to three equivalent Sc(1), three equivalent Ni(1), three equivalent Ni(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a body-centered cubic geometry to eight equivalent Ni(1) atoms. In the second Ge site, Ge(1) is bonded to four equivalent Sc(1), four equivalent Ni(1), and four equivalent Ni(2) atoms to form a mixture of corner and face-sharing GeSc4Ni8 cuboctahedra.
