Pu2Pt2Sn crystallizes in the tetragonal P4/mbm space group. Pu(1) is bonded in a 10-coordinate geometry to six equivalent Pt(1) and four equivalent Sn(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Pu(1), one Pt(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Pu(1) and four equivalent Pt(1) atoms to form a mixture of corner and face-sharing SnPu8Pt4 cuboctahedra.
Pu2Pt2Sn crystallizes in the tetragonal P4/mbm space group. Pu(1) is bonded in a 10-coordinate geometry to six equivalent Pt(1) and four equivalent Sn(1) atoms. There are two shorter (2.87 Å) and four longer (3.04 Å) Pu(1)-Pt(1) bond lengths. All Pu(1)-Sn(1) bond lengths are 3.43 Å. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Pu(1), one Pt(1), and two equivalent Sn(1) atoms. The Pt(1)-Pt(1) bond length is 2.80 Å. Both Pt(1)-Sn(1) bond lengths are 3.05 Å. Sn(1) is bonded to eight equivalent Pu(1) and four equivalent Pt(1) atoms to form a mixture of corner and face-sharing SnPu8Pt4 cuboctahedra.
