The structure described by Ta4Te9OI4 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four Ta4Te9OI4 clusters. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 1-coordinate geometry to one Te(1), one Te(2), one Te(3), one Te(4), one Te(5), one O(1), and one I(1) atom. In the second Ta site, Ta(2) is bonded in a distorted single-bond geometry to one Te(1), one Te(2), one Te(3), one Te(4), one O(1), and one I(2) atom. There are five inequivalent Te sites. In the first Te site, Te(1) is bonded in a 2-coordinate geometry to one Ta(1) and one Ta(2) atom. In the second Te site, Te(2) is bonded in a 2-coordinate geometry to one Ta(1) and one Ta(2) atom. In the third Te site, Te(3) is bonded in a 2-coordinate geometry to one Ta(1) and one Ta(2) atom. In the fourth Te site, Te(4) is bonded in a 2-coordinate geometry to one Ta(1) and one Ta(2) atom. In the fifth Te site, Te(5) is bonded in a 2-coordinate geometry to two equivalent Ta(1) atoms. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Ta(1) and two equivalent Ta(2) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one Ta(1) atom. In the second I site, I(2) is bonded in a single-bond geometry to one Ta(2) atom. is represented by the CIF card [CIF]
