'''Antimony triselenide''' is the [[chemical compound]] with the [[chemical formula|formula]] [[Antimony|Sb<sub>2</sub>]][[Selenium|Se<sub>3</sub>]]. 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. "First-principles study of the electronic properties of A<sub>2</sub>B<sub>3</sub> minerals,, with A=Bi,Sb and B=S,Se, Note: Hypothetical sulphosalt structure derived from density functional theory"" Physics and Chemistry of Minerals 2005, volume 32 p.295-300.</ref> I
