The material structure described by UCu2Sn crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded in a 6-coordinate geometry to six equivalent Cu(1) and six equivalent Sn(1) atoms. Cu(1) is bonded in a 8-coordinate geometry to three equivalent U(1), one Cu(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 14-coordinate geometry to six equivalent U(1) and eight equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
