The structure described by NdMn2Ge2 crystallizes in the tetragonal I4/mmm space group. Nd(1) is bonded in a 16-coordinate geometry to eight equivalent Mn(1) and eight equivalent Ge(1) atoms. Mn(1) is bonded to four equivalent Nd(1) and four equivalent Ge(1) atoms to form a mixture of edge, face, and corner-sharing MnNd4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), four equivalent Mn(1), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
