The compound described by In7Te10 crystallizes in the trigonal R32 space group. There are three inequivalent In sites. In the first In site, In(1) is bonded to one Te(2), one Te(3), and two equivalent Te(1) atoms to form InTe4 tetrahedra that share  a cornercorner with one In(3)InTe3 tetrahedra,  a cornercorner with one In(1)Te4 tetrahedra, corners with three equivalent In(2)Te4 tetrahedra, and  an edgeedge with one In(1)Te4 tetrahedra. In the second In site, In(2) is bonded to one Te(1), one Te(3), one Te(4), and one Te(5) atom to form InTe4 tetrahedra that share  a cornercorner with one In(3)InTe3 tetrahedra, corners with three equivalent In(1)Te4 tetrahedra, and corners with three equivalent In(2)Te4 tetrahedra. In the third In site, In(3) is bonded to one In(3) and three equivalent Te(3) atoms to form corner-sharing InInTe3 tetrahedra. There are five inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted T-shaped geometry to one In(2) and two equivalent In(1) atoms. In the second Te site, Te(2) is bonded in an L-shaped geometry to two equivalent In(1) atoms. In the third Te site, Te(3) is bonded in a trigonal non-coplanar geometry to one In(1), one In(2), and one In(3) atom. In the fourth Te site, Te(4) is bonded in a water-like geometry to two equivalent In(2) atoms. In the fifth Te site, Te(5) is bonded in a trigonal non-coplanar geometry to three equivalent In(2) atoms. is represented by the CIF card [CIF]
