Np2Pt2In crystallizes in the tetragonal P4/mbm space group. Np(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) and four equivalent In(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Np(1), one Pt(1), and two equivalent In(1) atoms. In(1) is bonded to eight equivalent Np(1) and four equivalent Pt(1) atoms to form a mixture of face and corner-sharing InNp8Pt4 cuboctahedra.
Np2Pt2In crystallizes in the tetragonal P4/mbm space group. Np(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) and four equivalent In(1) atoms. There are two shorter (2.87 Å) and four longer (3.03 Å) Np(1)-Pt(1) bond lengths. All Np(1)-In(1) bond lengths are 3.44 Å. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Np(1), one Pt(1), and two equivalent In(1) atoms. The Pt(1)-Pt(1) bond length is 2.86 Å. Both Pt(1)-In(1) bond lengths are 3.05 Å. In(1) is bonded to eight equivalent Np(1) and four equivalent Pt(1) atoms to form a mixture of face and corner-sharing InNp8Pt4 cuboctahedra.
