==Properties==
==Properties==
Bismuth(III) sulfide is [[isostructural]] with [[stibnite]] (stibnite is one of the forms of [[antimony(III) sulfide]]). Bismuth atoms are in two different environments, both of which have 7 coordinate Bismuth atoms, 4 in a near planar rectangle and three more distant making an irregular 7-coordination group.<ref>Wells A.F. (1984) ''Structural Inorganic Chemistry'', 5th edition Oxford Science Publications, {{ISBN|0-19-855370-6}}</ref>
Bismuth(III) sulfide has a trigonal prismatic crystal structure.

It can react with acids to produce the odoriferous [[hydrogen sulfide]] gas.
It can react with acids to produce the odoriferous [[hydrogen sulfide]] gas.

Bismuth(III) sulfide may be produced in the body by the reaction of the common gastrointestinal drug [[bismuth subsalicylate]] with naturally occurring sulfides; this causes temporary [[Black hairy tongue|black tongue]] when the sulfides are in the mouth and black feces when the sulfides are in the colon.
