The crystal structure described by SeCl is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four diselenium dichloride molecules. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted water-like geometry to one Se(2) and one Cl(1) atom. In the second Se site, Se(2) is bonded in a distorted water-like geometry to one Se(1) and one Cl(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Se(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Se(2) atom. is represented by the CIF file [CIF]
