MnNiGe crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded in a 11-coordinate geometry to five equivalent Ni(1) and six equivalent Ge(1) atoms. Ni(1) is bonded in a 11-coordinate geometry to five equivalent Mn(1) and six equivalent Ge(1) atoms. Ge(1) is bonded in a 14-coordinate geometry to six equivalent Mn(1), six equivalent Ni(1), and two equivalent Ge(1) atoms.
MnNiGe crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded in a 11-coordinate geometry to five equivalent Ni(1) and six equivalent Ge(1) atoms. There are three shorter (2.39 Å) and two longer (2.70 Å) Mn(1)-Ni(1) bond lengths. All Mn(1)-Ge(1) bond lengths are 2.75 Å. Ni(1) is bonded in a 11-coordinate geometry to five equivalent Mn(1) and six equivalent Ge(1) atoms. All Ni(1)-Ge(1) bond lengths are 2.75 Å. Ge(1) is bonded in a 14-coordinate geometry to six equivalent Mn(1), six equivalent Ni(1), and two equivalent Ge(1) atoms. Both Ge(1)-Ge(1) bond lengths are 2.70 Å.
