The structure described by Np(NiGe)2 crystallizes in the tetragonal I4/mmm space group. Np(1) is bonded in a 16-coordinate geometry to eight equivalent Ni(1) and eight equivalent Ge(1) atoms. Ni(1) is bonded in a 4-coordinate geometry to four equivalent Np(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Np(1), four equivalent Ni(1), and one Ge(1) atom. is represented by the CIF file [CIF]
