The material described by Ru2Sn3 crystallizes in the tetragonal P-4c2 space group. There are three inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 6-coordinate geometry to two equivalent Sn(2) and four equivalent Sn(1) atoms. In the second Ru site, Ru(2) is bonded in a 8-coordinate geometry to four equivalent Sn(1) and four equivalent Sn(2) atoms. In the third Ru site, Ru(3) is bonded in a distorted octahedral geometry to two equivalent Sn(2) and four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to one Ru(2), one Ru(3), and two equivalent Ru(1) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to one Ru(3), two equivalent Ru(1), and two equivalent Ru(2) atoms. is represented by the CIF card [CIF]
