AlCl4As3Se4 is Indium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight AlCl4 clusters and eight As3Se4 clusters. In each AlCl4 cluster, Al(1) is bonded in a tetrahedral geometry to one Cl(1), one Cl(2), one Cl(3), and one Cl(4) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a single-bond geometry to one Al(1) atom. In the second Cl site, Cl(3) is bonded in a single-bond geometry to one Al(1) atom. In the third Cl site, Cl(1) is bonded in a single-bond geometry to one Al(1) atom. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one Al(1) atom. In each As3Se4 cluster, there are three inequivalent As sites. In the first As site, As(1) is bonded in a 3-coordinate geometry to one As(2), one Se(1), and one Se(3) atom. In the second As site, As(2) is bonded in a 3-coordinate geometry to one As(1), one Se(1), and one Se(4) atom. In the third As site, As(3) is bonded in a distorted trigonal non-coplanar geometry to one Se(2), one Se(3), and one Se(4) atom. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded in a 3-coordinate geometry to one As(1), one As(2), and one Se(2) atom. In the second Se site, Se(2) is bonded in a water-like geometry to one As(3) and one Se(1) atom. In the third Se site, Se(3) is bonded in a water-like geometry to one As(1) and one As(3) atom. In the fourth Se site, Se(4) is bonded in a water-like geometry to one As(2) and one As(3) atom.
