· Sr4V2Se6O21

Sr4V2Se6O21 is a mixed-metal oxide-selenide semiconductor compound containing strontium, vanadium, and selenium. This is a research-phase material studied primarily in solid-state chemistry and materials science contexts, belonging to the family of polymetallic chalcogenides that show promise for electronic and photonic applications. The vanadium-containing framework and selenide coordination suggest potential utility in photocatalysis, optical devices, or energy conversion technologies, though industrial deployment remains exploratory.
