The structure described by BaYbSn3 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 10-coordinate geometry to two equivalent Sn(4), four equivalent Sn(1), and four equivalent Sn(2) atoms. In the second Ba site, Ba(2) is bonded in a 9-coordinate geometry to one Sn(3), two equivalent Sn(2), two equivalent Sn(4), and four equivalent Sn(1) atoms. Yb(1) is bonded in a 6-coordinate geometry to one Sn(4), two equivalent Sn(1), two equivalent Sn(3), and three equivalent Sn(2) atoms. There are four inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), two equivalent Yb(1), one Sn(2), one Sn(3), and one Sn(4) atom. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to one Ba(2), two equivalent Ba(1), three equivalent Yb(1), one Sn(1), and one Sn(2) atom. In the third Sn site, Sn(3) is bonded in a 8-coordinate geometry to one Ba(2), four equivalent Yb(1), one Sn(4), and two equivalent Sn(1) atoms. In the fourth Sn site, Sn(4) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), two equivalent Yb(1), one Sn(3), one Sn(4), and two equivalent Sn(1) atoms. is represented by the CIF file [CIF]
