BaCu2Te2 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 16-coordinate geometry to four equivalent Cu(1), five equivalent Cu(2), three equivalent Te(1), and four equivalent Te(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to four equivalent Ba(1), one Te(1), and three equivalent Te(2) atoms to form distorted CuBa4Te4 tetrahedra that share corners with six equivalent Cu(1)Ba4Te4 tetrahedra, corners with eight equivalent Cu(2)Ba5Te4 tetrahedra, edges with two equivalent Cu(1)Ba4Te4 tetrahedra, faces with two equivalent Cu(1)Ba4Te4 tetrahedra, and faces with six equivalent Cu(2)Ba5Te4 tetrahedra. In the second Cu site, Cu(2) is bonded to five equivalent Ba(1), one Te(2), and three equivalent Te(1) atoms to form distorted CuBa5Te4 tetrahedra that share corners with eight equivalent Cu(1)Ba4Te4 tetrahedra, corners with eight equivalent Cu(2)Ba5Te4 tetrahedra, edges with two equivalent Cu(2)Ba5Te4 tetrahedra, faces with four equivalent Cu(2)Ba5Te4 tetrahedra, and faces with six equivalent Cu(1)Ba4Te4 tetrahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to three equivalent Ba(1), one Cu(1), and three equivalent Cu(2) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1), one Cu(2), and three equivalent Cu(1) atoms.
BaCu2Te2 crystallizes in the orthorhombic Pnma space group.
