The compound described by BaCuSn2 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 14-coordinate geometry to four equivalent Cu(1), four equivalent Sn(2), and six equivalent Sn(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one 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 9-coordinate geometry to six equivalent Ba(1), one Cu(1), and two equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
