Stibnite

Crystal Structure of Stibnite. Stibnite is a compound of antimony (Sb) and sulfur (S), with the formula Sb 2 S 3. Stibnite is a member of the orthorhombic system, often occurring as long, prismatic 4-sided crystals with pyramidal terminations at each end. Crystals may be quite large, often resembling swords.
