FeMnGe crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded in a 14-coordinate geometry to two equivalent Mn(1), six equivalent Fe(1), and six equivalent Ge(1) atoms. Fe(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1) and five equivalent Ge(1) atoms. Ge(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1) and five equivalent Fe(1) atoms.
FeMnGe crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded in a 14-coordinate geometry to two equivalent Mn(1), six equivalent Fe(1), and six equivalent Ge(1) atoms. Both Mn(1)-Mn(1) bond lengths are 2.52 Å. All Mn(1)-Fe(1) bond lengths are 2.68 Å. All Mn(1)-Ge(1) bond lengths are 2.68 Å. Fe(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1) and five equivalent Ge(1) atoms. There are three shorter (2.37 Å) and two longer (2.52 Å) Fe(1)-Ge(1) bond lengths. Ge(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1) and five equivalent Fe(1) atoms.
