Mn3GeN crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Ge(1) and two equivalent N(1) atoms. In the second Mn site, Mn(2) is bonded in a distorted linear geometry to four equivalent Ge(1) and two equivalent N(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to four equivalent Mn(1) and four equivalent Mn(2) atoms. N(1) is bonded to two equivalent Mn(2) and four equivalent Mn(1) atoms to form corner-sharing NMn6 octahedra. The corner-sharing octahedral tilt angles range from 0-29°.

In the first Mn site, Mn(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Ge(1) and two equivalent N(1) atoms. Both Mn(1)-Ge(1) bond lengths are 2.46 Å. Both Mn(1)-N(1) bond lengths are 1.91 Å. In the second Mn site, Mn(2) is bonded in a distorted linear geometry to four equivalent Ge(1) and two equivalent N(1) atoms. All Mn(2)-Ge(1) bond lengths are 2.62 Å. Both Mn(2)-N(1) bond lengths are 2.03 Å. Ge(1) is bonded in a 8-coordinate geometry to four equivalent Mn(1) and four equivalent Mn(2) atoms. N(1) is bonded to two equivalent Mn(2) and four equivalent Mn(1) atoms to form corner-sharing NMn6 octahedra. The corner-sharing octahedral tilt angles range from 0-29°.
