The crystal structure described by NdMnFeGe2 crystallizes in the tetragonal I-4m2 space group. Nd(1) is bonded in a 16-coordinate geometry to four equivalent Mn(1), four equivalent Fe(1), and eight equivalent Ge(1) atoms. Mn(1) is bonded to four equivalent Nd(1), four equivalent Fe(1), and four equivalent Ge(1) atoms to form a mixture of distorted face and corner-sharing MnNd4Fe4Ge4 tetrahedra. Fe(1) is bonded in a 12-coordinate geometry to four equivalent Nd(1), four equivalent Mn(1), and four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), two equivalent Mn(1), two equivalent Fe(1), and one Ge(1) atom. is represented by the CIF file [CIF]
