The material described by CeCu2(Si0.5Ge0.5)2 crystallizes in the tetragonal I4mm space group. Ce(1) is bonded in a 16-coordinate geometry to eight equivalent Cu(1), four equivalent Ge(1), and four equivalent Si(1) atoms. Cu(1) is bonded in a 12-coordinate geometry to four equivalent Ce(1), four equivalent Cu(1), two equivalent Ge(1), and two equivalent Si(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), four equivalent Cu(1), and one Si(1) atom. Si(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), four equivalent Cu(1), and one Ge(1) atom. is represented by the CIF card [CIF]
