The material structure described by U3Cu3Sn4 crystallizes in the cubic I-43d space group. U(1) is bonded in a 12-coordinate geometry to four equivalent Cu(1) and eight equivalent Sn(1) atoms. Cu(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
