The material described by As4S3 is Indium-like structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four tetraarsenic trisulfide molecules. There are three inequivalent As sites. In the first As site, As(1) is bonded in a distorted single-bond geometry to one S(2) atom. In the second As site, As(2) is bonded in a distorted single-bond geometry to one S(1) atom. In the third As site, As(3) is bonded in a distorted trigonal non-coplanar geometry to one S(1) and two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a water-like geometry to one As(2) and one As(3) atom. In the second S site, S(2) is bonded in a water-like geometry to one As(1) and one As(3) atom. is represented by the CIF file [CIF]
