· Sr4 Cr2 Cu2 S2 O6

Sr₄Cr₂Cu₂S₂O₆ is a mixed-metal oxysulfide semiconductor compound combining strontium, chromium, and copper in an ordered crystal structure. This is a research-phase material studied primarily for its potential in photocatalysis and energy conversion applications, where the combination of transition metals (Cr, Cu) creates active sites for light-driven reactions. The oxysulfide class bridges conventional oxide and sulfide semiconductors, offering tunable bandgaps and potentially enhanced light absorption compared to pure oxide semiconductors, making it of interest for emerging technologies where conventional materials have performance limitations.
