The structure described by NpRu2Si2 crystallizes in the tetragonal I4/mmm space group. Np(1) is bonded in a 16-coordinate geometry to eight equivalent Ru(1) and eight equivalent Si(1) atoms. Ru(1) is bonded in a 4-coordinate geometry to four equivalent Np(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 4-coordinate geometry to four equivalent Np(1) and four equivalent Ru(1) atoms. is represented by the CIF file [CIF]
