Bismuth(III) sulfide is ] with ] (stibnite is one of the forms of ]). 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 ] gas. |

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