The crystal structure described by CeCuSi2 crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 10-coordinate geometry to four equivalent Cu(1), two equivalent Si(1), and four equivalent Si(2) atoms. Cu(1) is bonded in a 6-coordinate geometry to four equivalent Ce(1) and two equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 6-coordinate geometry to two equivalent Ce(1), two equivalent Cu(1), and two equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Si(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
