TaTeCl9 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four TaTeCl9 clusters. Ta(1) is bonded to one Cl(3), one Cl(4), one Cl(5), one Cl(6), one Cl(8), and one Cl(9) atom to form TaCl6 octahedra that share  a cornercorner with one Te(1)Cl6 octahedra and  an edgeedge with one Te(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 57°. Te(1) is bonded to one Cl(1), one Cl(2), one Cl(3), one Cl(6), one Cl(7), and one Cl(9) atom to form distorted TeCl6 octahedra that share  a cornercorner with one Ta(1)Cl6 octahedra and  an edgeedge with one Ta(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are nine inequivalent Cl sites. In the first Cl site, Cl(9) is bonded in a water-like geometry to one Ta(1) and one Te(1) atom. In the second Cl site, Cl(1) is bonded in a single-bond geometry to one Te(1) atom. In the third Cl site, Cl(2) is bonded in a single-bond geometry to one Te(1) atom. In the fourth Cl site, Cl(3) is bonded in a water-like geometry to one Ta(1) and one Te(1) atom. In the fifth Cl site, Cl(4) is bonded in a single-bond geometry to one Ta(1) atom. In the sixth Cl site, Cl(5) is bonded in a single-bond geometry to one Ta(1) atom. In the seventh Cl site, Cl(6) is bonded in a distorted single-bond geometry to one Ta(1) and one Te(1) atom. In the eighth Cl site, Cl(7) is bonded in a single-bond geometry to one Te(1) atom. In the ninth Cl site, Cl(8) is bonded in a single-bond geometry to one Ta(1) atom.
