Sc3Ni11Ge4 crystallizes in the hexagonal P6_3/mmc space group. Sc(1) is bonded in a 14-coordinate geometry to two equivalent Ni(2), two equivalent Ni(3), six equivalent Ni(1), and four equivalent Ge(1) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 12-coordinate geometry to three equivalent Sc(1), one Ni(2), two equivalent Ni(3), three equivalent Ni(1), one Ge(2), and two 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(3), and three equivalent Ge(1) atoms. In the third Ni site, Ni(3) is bonded in a 12-coordinate geometry to two equivalent Sc(1), two equivalent Ni(2), two equivalent Ni(3), four equivalent Ni(1), and two equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. In the second Ge site, Ge(1) is bonded to four equivalent Sc(1), two equivalent Ni(2), two equivalent Ni(3), and four equivalent Ni(1) atoms to form a mixture of distorted face and corner-sharing GeSc4Ni8 cuboctahedra.
