Materials Data on NpNi2 by Materials Project
NpNi2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Np is bonded in a 12-coordinate geometry to twelve equivalent Ni atoms. All Np–Ni bond lengths are 2.87 Å. Ni is bonded to six equivalent Np and six equivalent Ni atoms to form a mixture of corner, edge, and face-sharing NiNp6Ni6 cuboctahedra. All Ni–Ni bond lengths are 2.45 Å.
