Np2Ni2In crystallizes in the tetragonal P4/mbm space group. Np(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent In(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Np(1), one Ni(1), and two equivalent In(1) atoms. In(1) is bonded to eight equivalent Np(1) and four equivalent Ni(1) atoms to form a mixture of face and corner-sharing InNp8Ni4 cuboctahedra.
Np2Ni2In crystallizes in the tetragonal P4/mbm space group. Np(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent In(1) atoms. There are two shorter (2.77 Å) and four longer (2.86 Å) Np(1)-Ni(1) bond lengths. All Np(1)-In(1) bond lengths are 3.27 Å. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Np(1), one Ni(1), and two equivalent In(1) atoms. The Ni(1)-Ni(1) bond length is 2.63 Å. Both Ni(1)-In(1) bond lengths are 2.90 Å. In(1) is bonded to eight equivalent Np(1) and four equivalent Ni(1) atoms to form a mixture of face and corner-sharing InNp8Ni4 cuboctahedra.
