Abstract

A family of five hybrid ABX3 perovskites have been synthesized using hypophosphite (H2POO)3 as the X-site ion. These compounds adopt the general formula [Am]Mn(H2POO)3, where Am = guanidinium (HUA), formamidinium (FA), imidazolium (IM), triazolium (TRZ), and dabconium (DAB). We explore the diverse structural and phase transition behaviors of these materials through single-crystal diffraction measurements and demonstrate contrasting magnetism in two of the phases, Am = GUA and FA, that arises from structural distortions. The results show that hypophosphite perovskites offer a promising platform for generating new functional materials.
