Mn5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. In the second Mn site, Mn(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Mn(2) and five equivalent Mn(1) atoms.
Mn5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. There are a spread of Mn(1)-Ge(1) bond distances ranging from 2.48-2.73 Å. In the second Mn site, Mn(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. All Mn(2)-Ge(1) bond lengths are 2.54 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Mn(2) and five equivalent Mn(1) atoms.
