MnCuInTe3 is Stannite-like structured and crystallizes in the monoclinic Cm space group. Mn(1) is bonded to one Te(1), one Te(3), and two equivalent Te(2) atoms to form MnTe4 tetrahedra that share corners with two equivalent Mn(1)Te4 tetrahedra, corners with five equivalent Cu(1)Te4 tetrahedra, and corners with five equivalent In(1)Te4 tetrahedra. Cu(1) is bonded to one Te(2), one Te(3), and two equivalent Te(1) atoms to form CuTe4 tetrahedra that share corners with two equivalent Cu(1)Te4 tetrahedra, corners with five equivalent Mn(1)Te4 tetrahedra, and corners with five equivalent In(1)Te4 tetrahedra. In(1) is bonded to one Te(1), one Te(2), and two equivalent Te(3) atoms to form InTe4 tetrahedra that share corners with two equivalent In(1)Te4 tetrahedra, corners with five equivalent Mn(1)Te4 tetrahedra, and corners with five equivalent Cu(1)Te4 tetrahedra.
