The structure described by NdMn2 is Hexagonal Laves structured and crystallizes in the orthorhombic Cmcm space group. Nd(1) is bonded in a 16-coordinate geometry to four equivalent Nd(1), three equivalent Mn(1), three equivalent Mn(2), and six equivalent Mn(3) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent Nd(1), two equivalent Mn(2), and four equivalent Mn(3) atoms to form a mixture of corner, face, and edge-sharing MnNd6Mn6 cuboctahedra. In the second Mn site, Mn(2) is bonded to six equivalent Nd(1), two equivalent Mn(1), and four equivalent Mn(3) atoms to form a mixture of corner, face, and edge-sharing MnNd6Mn6 cuboctahedra. In the third Mn site, Mn(3) is bonded to six equivalent Nd(1), two equivalent Mn(1), two equivalent Mn(2), and two equivalent Mn(3) atoms to form a mixture of corner, face, and edge-sharing MnNd6Mn6 cuboctahedra. is represented by the CIF file [CIF]
