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.
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. There are four shorter (3.54 Å) and two longer (3.79 Å) Na(1)-Na(1) bond lengths. There are two shorter (3.64 Å) and two longer (3.93 Å) Na(1)-Pu(1) bond lengths. Pu(1) is bonded to twelve equivalent Na(1) atoms to form a mixture of corner and face-sharing PuNa12 cuboctahedra.
