Materials Data on Np(CrGe)2 by Materials Project
Np(CrGe)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 Ge atoms. All Np–Ge bond lengths are 3.03 Å. Cr is bonded to four equivalent Ge atoms to form a mixture of edge and corner-sharing CrGe4 tetrahedra. All Cr–Ge bond lengths are 2.45 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Np, four equivalent Cr, and one Ge atom. The Ge–Ge bond length is 2.56 Å.
