EuCu2Sn2 crystallizes in the monoclinic C2/m space group. Eu(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and eight equivalent Sn(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1), two equivalent Cu(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), four equivalent Cu(1), and one Sn(1) atom.
EuCu2Sn2 crystallizes in the monoclinic C2/m space group. Eu(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and eight equivalent Sn(1) atoms. There are two shorter (3.17 Å) and four longer (3.35 Å) Eu(1)-Cu(1) bond lengths. There are four shorter (3.43 Å) and four longer (3.65 Å) Eu(1)-Sn(1) bond lengths. Cu(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1), two equivalent Cu(1), and four equivalent Sn(1) atoms. Both Cu(1)-Cu(1) bond lengths are 2.58 Å. There are a spread of Cu(1)-Sn(1) bond distances ranging from 2.59-2.65 Å. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), four equivalent Cu(1), and one Sn(1) atom. The Sn(1)-Sn(1) bond length is 3.00 Å.
