The material exists as the [[sulfosalt]] [[mineral]] antimonselite, which crystallizes in an orthorhombic [[space group]].<ref>Jambor, J. L.; Grew, E. S."New Mineral Names" American Mineralogist, Volume 79, pages 387-391, 1994.</ref> In this compound, antimony is assigned the [[oxidation state]] 3+ and selenium 2-, but in fact the bonding in this compound is highly covalent as reflected by the black color and semiconducting properties of this and related materials.<ref>Caracas, R.; Gonze, X.
