· Sr3 Co2 Cu2 S2 O5

Sr3Co2Cu2S2O5 is an oxysulfide semiconductor compound combining strontium, cobalt, copper, and sulfur in a mixed-valence structure. This is a research-phase material being investigated for potential photocatalytic and thermoelectric applications, where the combination of transition metals (Co, Cu) and chalcogenide bonding offers tunable electronic properties distinct from purely oxide or sulfide alternatives.
