The compound described by CeAg3Al2 crystallizes in the orthorhombic Cmmm space group. Ce(1) is bonded in a 18-coordinate geometry to four equivalent Ag(2), six equivalent Ag(1), and eight equivalent Al(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(2) is bonded to four equivalent Ce(1), four equivalent Ag(1), and four equivalent Al(1) atoms to form a mixture of distorted corner, edge, and face-sharing AgCe4Al4Ag4 cuboctahedra. In the second Ag site, Ag(1) is bonded in a 7-coordinate geometry to three equivalent Ce(1), two equivalent Ag(2), and four equivalent Al(1) atoms. Al(1) is bonded in a 12-coordinate geometry to four equivalent Ce(1), two equivalent Ag(2), four equivalent Ag(1), and two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
