SrCuSn2 crystallizes in the orthorhombic Cmcm space group. Sr(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 Sr(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 8-coordinate geometry to four equivalent Sr(1) and four equivalent Cu(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to six equivalent Sr(1), one Cu(1), and two equivalent Sn(2) atoms.
SrCuSn2 crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 14-coordinate geometry to four equivalent Cu(1), four equivalent Sn(1), and six equivalent Sn(2) atoms. All Sr(1)-Cu(1) bond lengths are 3.50 Å. There are two shorter (3.58 Å) and two longer (3.59 Å) Sr(1)-Sn(1) bond lengths. There are four shorter (3.48 Å) and two longer (3.74 Å) Sr(1)-Sn(2) bond lengths. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Sn(2), and four equivalent Sn(1) atoms. The Cu(1)-Sn(2) bond length is 2.57 Å. There are two shorter (2.69 Å) and two longer (2.73 Å) Cu(1)-Sn(1) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Cu(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to six equivalent Sr(1), one Cu(1), and two equivalent Sn(2) atoms. Both Sn(2)-Sn(2) bond lengths are 2.83 Å.
