The material structure described by CaMnFeGe2 crystallizes in the tetragonal I-4m2 space group. Ca(1) is bonded in a 8-coordinate geometry to four equivalent Fe(1) and eight equivalent Ge(1) atoms. Mn(1) is bonded to four equivalent Fe(1) and four equivalent Ge(1) atoms to form a mixture of distorted corner and face-sharing MnFe4Ge4 tetrahedra. Fe(1) is bonded in a 12-coordinate geometry to four equivalent Ca(1), four equivalent Mn(1), and four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ca(1), two equivalent Mn(1), two equivalent Fe(1), and one Ge(1) atom. is represented by the CIF file [CIF]
