Ba(RuSn2)3 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent Sn(2) and four equivalent Sn(4) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a 7-coordinate geometry to one Sn(1) and six equivalent Sn(2) atoms. In the second Ru site, Ru(1) is bonded in a 7-coordinate geometry to one Sn(1), three equivalent Sn(3), and three equivalent Sn(4) atoms. There are four inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 3-coordinate geometry to one Ru(2) and two equivalent Ru(1) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to two equivalent Ba(1) and three equivalent Ru(2) atoms. In the third Sn site, Sn(3) is bonded in a 6-coordinate geometry to six equivalent Ru(1) atoms. In the fourth Sn site, Sn(4) is bonded in a 5-coordinate geometry to two equivalent Ba(1) and three equivalent Ru(1) atoms.
