The structure described by NpPt3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Np(1) is bonded to twelve equivalent Pt(1) atoms to form a mixture of corner and face-sharing NpPt12 cuboctahedra. Pt(1) is bonded to four equivalent Np(1) atoms to form a mixture of distorted corner, edge, and face-sharing PtNp4 cuboctahedra. is represented by the CIF card [CIF]
