CuTa2InTe4 is Stannite structured and crystallizes in the tetragonal I-42m space group. Ta(1) is bonded to four equivalent Te(1) atoms to form TaTe4 tetrahedra that share corners with four equivalent Ta(1)Te4 tetrahedra, corners with four equivalent Cu(1)Te4 tetrahedra, and corners with four equivalent In(1)Te4 tetrahedra. Cu(1) is bonded to four equivalent Te(1) atoms to form CuTe4 tetrahedra that share corners with four equivalent In(1)Te4 tetrahedra and corners with eight equivalent Ta(1)Te4 tetrahedra. In(1) is bonded to four equivalent Te(1) atoms to form InTe4 tetrahedra that share corners with four equivalent Cu(1)Te4 tetrahedra and corners with eight equivalent Ta(1)Te4 tetrahedra. Te(1) is bonded to two equivalent Ta(1), one Cu(1), and one In(1) atom to form corner-sharing TeTa2InCu tetrahedra.
