The compound described by Na3Pu crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded in a 10-coordinate geometry to six equivalent Na(1) and four equivalent Pu(1) atoms. Pu(1) is bonded to twelve equivalent Na(1) atoms to form a mixture of corner and face-sharing PuNa12 cuboctahedra. is represented by the CIF file [CIF]
