The material described by USSe crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 8-coordinate geometry to four equivalent Se(1) and four equivalent S(1) atoms. Se(1) is bonded to four equivalent U(1) atoms to form a mixture of distorted edge and corner-sharing SeU4 tetrahedra. S(1) is bonded in a square co-planar geometry to four equivalent U(1) atoms. is represented by the CIF file [CIF]
