KIn(TeO3)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.83–3.03 Å. In3+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of In–O bond distances ranging from 2.18–2.22 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.90–2.86 Å. In the second Te4+ site, Te4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.89 Å) and one longer (1.90 Å) Te–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one In3+ and two Te4+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one In3+, and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent K1+, one In3+, and one Te4+ atom. In the fourth O2- site, O2- is bonded to two equivalent K1+, one In3+, and one Te4+ atom to form a mixture of distorted corner and edge-sharing OK2InTe tetrahedra.
