Abstract: Following the recent discovery of a new family of hybrid ABX <subscript>3</subscript> perovskites where X=(H <subscript>2</subscript> POO) <superscript>-</superscript> (hypophosphite), this work reports a facile synthesis for mixed X-site formate perovskites of composition [GUA]Mn(HCOO) <subscript>3-x</subscript> (H <subscript>2</subscript> POO) <subscript>x</subscript> , 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.<br /> (© 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.)
