In3Te4Sb is I4/mcm-derived structured and crystallizes in the tetragonal I422 space group. The structure consists of two 7440-36-0 atoms inside a In3Te4 framework. In the In3Te4 framework, there are two inequivalent In sites. In the first In site, In(1) is bonded in a 8-coordinate geometry to eight equivalent Te(1) atoms. In the second In site, In(2) is bonded to four equivalent Te(1) atoms to form edge-sharing InTe4 tetrahedra. Te(1) is bonded in a 2-coordinate geometry to two equivalent In(1) and two equivalent In(2) atoms.
