Nb4Te9OI4 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four Nb4Te9OI4 clusters. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a distorted single-bond 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 Nb site, Nb(2) is bonded in a distorted single-bond geometry to one Te(1), one Te(2), one Te(3), one Te(5), 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 Nb(1), one Nb(2), and one Te(2) atom. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to one Nb(1), one Nb(2), and one Te(1) atom. In the third Te site, Te(3) is bonded in a 2-coordinate geometry to one Nb(1) and one Nb(2) atom. In the fourth Te site, Te(4) is bonded in a 2-coordinate geometry to two equivalent Nb(1) atoms. In the fifth Te site, Te(5) is bonded in a 2-coordinate geometry to one Nb(1) and one Nb(2) atom. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Nb(1) and two equivalent Nb(2) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one Nb(1) atom. In the second I site, I(2) is bonded in a single-bond geometry to one Nb(2) atom.
