A family of five hybrid ABX3 perovskites has been
synthesized using hypophosphite (H2POO)- 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 behavior 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.
