Materials Data on Np(GeRh)2 by Materials Project
Np(RhGe)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 Rh and eight equivalent Ge atoms. All Np–Rh bond lengths are 3.35 Å. All Np–Ge bond lengths are 3.18 Å. Rh is bonded to four equivalent Np and four equivalent Ge atoms to form a mixture of distorted edge, corner, and face-sharing RhNp4Ge4 tetrahedra. All Rh–Ge bond lengths are 2.47 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Np, four equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.56 Å.
