The compound described by VCu3Te3Se is Sulvanite-derived structured and crystallizes in the trigonal R3m space group. V(1) is bonded to six equivalent Cu(1), three equivalent Te(1), and one Se(1) atom to form distorted VCu6Te3Se tetrahedra that share corners with three equivalent Se(1)VCu3 tetrahedra, corners with six equivalent V(1)Cu6Te3Se tetrahedra, corners with nine equivalent Te(1)VCu3 tetrahedra,  a faceface with one Se(1)VCu3 tetrahedra, and faces with three equivalent Te(1)VCu3 tetrahedra. Cu(1) is bonded in a 6-coordinate geometry to two equivalent V(1), three equivalent Te(1), and one Se(1) atom. Te(1) is bonded to one V(1) and three equivalent Cu(1) atoms to form TeVCu3 tetrahedra that share corners with two equivalent Se(1)VCu3 tetrahedra, corners with three equivalent V(1)Cu6Te3Se tetrahedra, corners with four equivalent Te(1)VCu3 tetrahedra,  an edgeedge with one Se(1)VCu3 tetrahedra, edges with two equivalent Te(1)VCu3 tetrahedra, and  a faceface with one V(1)Cu6Te3Se tetrahedra. Se(1) is bonded to one V(1) and three equivalent Cu(1) atoms to form distorted SeVCu3 tetrahedra that share corners with three equivalent V(1)Cu6Te3Se tetrahedra, corners with six equivalent Te(1)VCu3 tetrahedra, edges with three equivalent Te(1)VCu3 tetrahedra, and  a faceface with one V(1)Cu6Te3Se tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
