The structure described by SiSe2 is Cyanogen Chloride-derived structured and crystallizes in the orthorhombic Ibam space group. The structure is zero-dimensional and consists of four si se2 molecules. Si(1) is bonded in a linear geometry to two equivalent Se(1) atoms. Se(1) is bonded in a single-bond geometry to one Si(1) atom. is represented by the CIF file [CIF]
