The structure described by Mn5Fe5C4 crystallizes in the triclinic P1 space group. There are five inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 2-coordinate geometry to one C(1), one C(2), and one C(3) atom.

In the third Mn site, Mn(3) is bonded in a 3-coordinate geometry to one C(1), one C(3), and one C(4) atom. In the fourth Mn site, Mn(4) is bonded to one C(1), one C(2), one C(3), and one C(4) atom to form distorted edge-sharing MnC4 tetrahedra. In the fifth Mn site, Mn(5) is bonded to one C(1), one C(2), one C(3), and one C(4) atom to form distorted edge-sharing MnC4 tetrahedra. There are five inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted bent 150 degrees geometry to one C(1) and one C(4) atom. In the second Fe site, Fe(2) is bonded in a distorted bent 150 degrees geometry to one C(2) and one C(3) atom.
