The compound described by EuCuSn2 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 14-coordinate geometry to four equivalent Cu(1), four equivalent Sn(1), and six equivalent Sn(2) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one 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 four equivalent Eu(1) and four equivalent Cu(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to six equivalent Eu(1), one Cu(1), and two equivalent Sn(2) atoms. is represented by the CIF file [CIF]
