Patronite is the vanadium sulfide mineral with formula VS4. The material is usually described as V(S2)2. Structurally, it is a "linear-chain" compound with alternating bonding and nonbonding contacts between the vanadium centers. The vanadium is octa-coordinated, which is an uncommon geometry for this metal.
