Designing a new family of oxonium-cation based structurally diverse organic–inorganic hybrid iodoantimonate crystals

Several new structurally diverse carbonyl functional group-based iodoantimonate organic-inorganic hybrid crystals are synthesized using an in situ formed oxonium cationic precursor. These crystals exhibit interesting optoelectronic properties consistent with DFT calculations. Charge transfer and photoluminescence quenching between these crystals and Au nanoparticulate films are examined for potential application interest.
