The compound described by Ru3Sn7 crystallizes in the cubic Im-3m space group. Ru(1) is bonded in a 8-coordinate geometry to four 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 four equivalent Ru(1) atoms. In the second Sn site, Sn(2) is bonded in a 7-coordinate geometry to three equivalent Ru(1) and four equivalent Sn(2) atoms. is represented by the CIF file [CIF]
