Mn3Ge is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to four equivalent Mn(2) and four equivalent Ge(1) atoms to form a mixture of distorted face, corner, and edge-sharing MnMn4Ge4 tetrahedra. In the second Mn site, Mn(2) is bonded in a 14-coordinate geometry to eight equivalent Mn(1) and six equivalent Ge(1) atoms. Ge(1) is bonded in a distorted body-centered cubic geometry to six equivalent Mn(2) and eight equivalent Mn(1) atoms.

In the first Mn site, Mn(1) is bonded to four equivalent Mn(2) and four equivalent Ge(1) atoms to form a mixture of distorted face, corner, and edge-sharing MnMn4Ge4 tetrahedra. All Mn(1)-Mn(2) bond lengths are 2.50 Å. All Mn(1)-Ge(1) bond lengths are 2.50 Å. In the second Mn site, Mn(2) is bonded in a 14-coordinate geometry to eight equivalent Mn(1) and six equivalent Ge(1) atoms. All Mn(2)-Ge(1) bond lengths are 2.88 Å. Ge(1) is bonded in a distorted body-centered cubic geometry to six equivalent Mn(2) and eight equivalent Mn(1) atoms.
