NdPt5 crystallizes in the hexagonal P6/mmm space group. Nd(1) is bonded in a distorted hexagonal planar geometry to six equivalent Pt(1) and twelve equivalent Pt(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to three equivalent Nd(1) and six equivalent Pt(2) atoms. In the second Pt site, Pt(2) is bonded to four equivalent Nd(1), four equivalent Pt(1), and four equivalent Pt(2) atoms to form a mixture of edge, face, and corner-sharing PtNd4Pt8 cuboctahedra.
