The material described by Np(RhSi)2 crystallizes in the tetragonal I4/mmm space group. Np(1) is bonded in a 16-coordinate geometry to eight equivalent Rh(1) and eight equivalent Si(1) atoms. Rh(1) is bonded to four equivalent Np(1) and four equivalent Si(1) atoms to form a mixture of distorted edge, corner, and face-sharing RhNp4Si4 tetrahedra. Si(1) is bonded in a 9-coordinate geometry to four equivalent Np(1), four equivalent Rh(1), and one Si(1) atom. is represented by the CIF card [CIF]
