Patrónite is the vanadium sulfide mineral with formula VS4. The material is usually described as V4+(S22−)2.[6] 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.[7]
The mineral was first described in 1906 for an occurrence in the Minas Ragra vanadium mine near Junín, Cerro de Pasco, Peru. It was named for Peruvian metallurgist Antenor Rizo-Patron (1866–1948) the discoverer of the deposit.[3][4] At the type locality in Peru it occurs in fissures within a red shale likely derived from an asphaltum deposit. Associated minerals include, native sulfur, bravoite, pyrite, minasragrite, stanleyite, dwornikite, quartz and vanadium bearing lignite.[4] It has also been reported from the Yushkinite gorge on the Middle Silova-Yakha River on the Paikhoi Range of the polar Urals of Russia and from the Tsumeb mine in Namibia.[3]
