The crystal structure described by Ce(Re2Si)2 crystallizes in the orthorhombic Cmmm space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Re(1), four equivalent Re(2), and eight equivalent Si(1) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 8-coordinate geometry to two equivalent Ce(1), two equivalent Re(1), six equivalent Re(2), and two equivalent Si(1) atoms. In the second Re site, Re(2) is bonded to two equivalent Ce(1), two equivalent Re(2), six equivalent Re(1), and two equivalent Si(1) atoms to form a mixture of distorted corner, edge, and face-sharing ReCe2Re8Si2 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), two equivalent Re(1), two equivalent Re(2), and one Si(1) atom. is represented by the CIF card [CIF]
