The compound described by TaCu3Te4 is Sulvanite structured and crystallizes in the cubic P-43m space group. Ta(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent Te(1) atoms. Cu(1) is bonded in a 6-coordinate geometry to two equivalent Ta(1) and four equivalent Te(1) atoms. Te(1) is bonded to one Ta(1) and three equivalent Cu(1) atoms to form a mixture of corner and edge-sharing TeTaCu3 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
