(FA)PbI₃ (FA = CH(NH₂)₂) has attracted attention for perovskite solar cells. However, its low stability at room temperature is a difficulty for application. Here, we report the synthesis of a novel FA-based hybrid perovskite compound containing SCN^- anion. Crystal structure analysis for obtained powder and single crystals revealed the superlattice structure. We discuss the effect of SCN^- substitution for stabilizing the perovskite phase.
