Abstract

Following the recent discovery of a new family of hybrid ABX₃ perovskites where X = (H₂POO) (hypophosphite), this work reports a facile synthesis for mixed X-site formate perovskites of composition [GUA]Mn(H-COO)_{3 x} (H₂ POO)_x, with two crystallographically distinct, partially ordered intermediate phases with x = 0.84 and 1.53, corresponding to ca. 30 and 50 mol % hypophosphite, respectively. These phases are characterised by single-crystal XRD and solid-state NMR spectroscopy, and their magnetic properties are reported.
