CeRu4Sn6 crystallizes in the tetragonal I-42m space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ru(1), four equivalent Sn(1), and eight equivalent Sn(2) atoms. Ru(1) is bonded in a 7-coordinate geometry to one Ce(1), two equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to two equivalent Ce(1) and four equivalent Ru(1) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to two equivalent Ce(1) and four equivalent Ru(1) atoms.
