The material structure described by Lu3(CuSn)4 crystallizes in the monoclinic C2/m space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 13-coordinate geometry to three equivalent Cu(1), three equivalent Cu(2), three equivalent Sn(1), and four equivalent Sn(2) atoms. In the second Lu site, Lu(2) is bonded in a 6-coordinate geometry to four equivalent Cu(2), two equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 10-coordinate geometry to three equivalent Lu(1), one Cu(2), two equivalent Cu(1), one Sn(2), and three equivalent Sn(1) atoms. In the second Cu site, Cu(2) is bonded in a 10-coordinate geometry to two equivalent Lu(2), three equivalent Lu(1), one Cu(1), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to one Lu(2), three equivalent Lu(1), three equivalent Cu(1), and three equivalent Cu(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Lu(2), four equivalent Lu(1), one Cu(1), one Cu(2), and one Sn(2) atom. is represented by the CIF card [CIF]
