Mn4FeGe3 crystallizes in the trigonal P-31m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 8-coordinate geometry to two equivalent Fe(1) and six equivalent Ge(1) atoms. In the second Mn site, Mn(2) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. Fe(1) is bonded in a 8-coordinate geometry to two equivalent Mn(1) and six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Mn(1), five equivalent Mn(2), and two equivalent Fe(1) atoms.
