N1 - Funding Information:
We are very grateful to Dr. D. L. Cruickshank and Dr. Z. A. Gál at Rigaku Oxford Diffraction for their help collecting very good quality SCXRD data on HP50 using the XtaLAB Synergy-S diffractometer with a HyPix-6000HE detector. Y.W. and A.K.C. gratefully thank the Ras Al Khaimah Center for Advanced Materials for financial support. Support for this work by Academic Fund Tier 1 NUS (R-284-000146-112) is acknowledged. M.W.G. thanks the Leverhulme Trust for funding via the Leverhulme Research Centre for Functional Materials Design. S.S. gratefully thanks the Winston Churchill Foundation of the USA for financial support. D.M.H. and I.D.S. are grateful for support from NECCES, an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences under Award No. DE-SC0012583. We thank Dr. M. J. Cliffe for helpful discussions, and for his help in fitting and plotting magnetic data.

N2 - 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.
