The material structure described by Ce2Ru2Al crystallizes in the orthorhombic Cmce space group. Ce(1) is bonded in a 4-coordinate geometry to four equivalent Ru(1) atoms. Ru(1) is bonded in a 6-coordinate geometry to four equivalent Ce(1) and two equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to four equivalent Ru(1) atoms. is represented by the CIF file [CIF]
