MgCe(NiH)4 crystallizes in the cubic F-43m space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Ce(1) and twelve equivalent Ni(1) atoms. Ce(1) is bonded to four equivalent Mg(1) and four equivalent H(1) atoms to form corner-sharing CeMg4H4 tetrahedra. Ni(1) is bonded in a 3-coordinate geometry to three equivalent Mg(1) and three equivalent H(1) atoms. H(1) is bonded to one Ce(1) and three equivalent Ni(1) atoms to form a mixture of corner and edge-sharing HCeNi3 tetrahedra.
