Materials Data on Np(NiGe)2 by Materials Project
Np(NiGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Np is bonded in a 8-coordinate geometry to eight equivalent Ni and eight equivalent Ge atoms. All Np–Ni bond lengths are 3.21 Å. All Np–Ge bond lengths are 3.12 Å. Ni is bonded to four equivalent Np and four equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing NiNp4Ge4 tetrahedra. All Ni–Ge bond lengths are 2.36 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Np, four equivalent Ni, and one Ge atom. The Ge–Ge bond length is 2.52 Å.
