In4Te3 crystallizes in the orthorhombic Pnnm space group. There are four inequivalent In sites. In the first In site, In(1) is bonded to one In(2), one Te(2), and two equivalent Te(3) atoms to form distorted InInTe3 tetrahedra that share corners with two equivalent In(1)InTe3 tetrahedra, corners with three equivalent In(4)InTe3 tetrahedra, and corners with two equivalent In(2)In2Te2 trigonal pyramids. In the second In site, In(2) is bonded to one In(1), one In(4), and two equivalent Te(2) atoms to form distorted InIn2Te2 trigonal pyramids that share corners with two equivalent In(1)InTe3 tetrahedra and corners with two equivalent In(2)In2Te2 trigonal pyramids. In the third In site, In(3) is bonded in a 3-coordinate geometry to one Te(1) and two equivalent Te(2) atoms. In the fourth In site, In(4) is bonded to one In(2), one Te(3), and two equivalent Te(1) atoms to form distorted corner-sharing InInTe3 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted T-shaped geometry to one In(3) and two equivalent In(4) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to one In(1), two equivalent In(2), and two equivalent In(3) atoms. In the third Te site, Te(3) is bonded in a 3-coordinate geometry to one In(4) and two equivalent In(1) atoms.
