The material described by Al2Cl7(Te)2 is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two tellurium tetramer molecules and four Al2Cl7 clusters. In each Al2Cl7 cluster, there are two inequivalent Al sites. In the first Al site, Al(1) is bonded to one Cl(1), one Cl(2), one Cl(3), and one Cl(4) atom to form corner-sharing AlCl4 tetrahedra. In the second Al site, Al(2) is bonded to one Cl(4), one Cl(5), one Cl(6), and one Cl(7) atom to form corner-sharing AlCl4 tetrahedra. There are seven inequivalent Cl sites. In the first Cl site, Cl(5) is bonded in a single-bond geometry to one Al(2) atom. In the second Cl site, Cl(6) is bonded in a single-bond geometry to one Al(2) atom. In the third Cl site, Cl(7) is bonded in a single-bond geometry to one Al(2) atom. In the fourth Cl site, Cl(1) is bonded in a single-bond geometry to one Al(1) atom. In the fifth Cl site, Cl(2) is bonded in a single-bond geometry to one Al(1) atom. In the sixth Cl site, Cl(3) is bonded in a single-bond geometry to one Al(1) atom. In the seventh Cl site, Cl(4) is bonded in a water-like geometry to one Al(1) and one Al(2) atom. is represented by the CIF file [CIF]
