ScMnGe crystallizes in the hexagonal P-62m space group. Sc(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1), one Ge(2), and four equivalent Ge(1) atoms. Mn(1) is bonded in a 4-coordinate geometry to six equivalent Sc(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Mn(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1) and three equivalent Mn(1) atoms.
ScMnGe crystallizes in the hexagonal P-62m space group. Sc(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1), one Ge(2), and four equivalent Ge(1) atoms. There are two shorter (3.04 Å) and four longer (3.13 Å) Sc(1)-Mn(1) bond lengths. The Sc(1)-Ge(2) bond length is 2.80 Å. All Sc(1)-Ge(1) bond lengths are 2.84 Å. Mn(1) is bonded in a 4-coordinate geometry to six equivalent Sc(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. Both Mn(1)-Ge(1) bond lengths are 2.61 Å. Both Mn(1)-Ge(2) bond lengths are 2.59 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Mn(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Sc(1) and three equivalent Mn(1) atoms.
