The crystal structure described by SmNd(MnGe)4 crystallizes in the tetragonal P4/mmm space group. Sm(1) is bonded in a 8-coordinate geometry to eight equivalent Ge(2) atoms. Nd(1) is bonded in a 8-coordinate geometry to eight equivalent Ge(1) atoms. Mn(1) is bonded to two equivalent Ge(1) and two equivalent Ge(2) atoms to form a mixture of edge and corner-sharing MnGe4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), four equivalent Mn(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent Sm(1), four equivalent Mn(1), and one Ge(2) atom. is represented by the CIF file [CIF]
