N1 - LVS and ANV acknowledge support by Megagrant program of the Government of Russian Federation through the project 15-075-2021-604 for the thermodynamic investigation. AShS, IAT and SSF appreciate support by Russian Science Foundation (Grant 23-73-10125) for the design, synthesis and material characterization. The research was carried out within the framework of the scientific program of the National Centre of Physics and Mathematics under the project “Research in strong and superstrong magnetic fields”. PZV thanks for support the Ministry of Science and Higher Education of the Russian Federation (theme “Spin” No. 122021000036-3). The authors are grateful to Dr. A. Volkov for fruitful discussions and to AICF at Skoltech for providing access to electron microscopy equipment.

N2 - A novel vanadium hydroxide-phosphate, NH4VPO4OH, was synthesized hydrothermally in V2O5−NH4H2PO4-citric acid system at 230 °C. It was characterized by XRD, TG-DSC, SEM-EDX, FTIR and NMR spectroscopy. NH4VPO4OH is isostructural with NH4GaPO4OH and features edge-sharing chains of VO6 octahedra. These chains running along [010] direction of the unit cell are connected by phosphate tetrahedra to form infinite layers parallel to the (100) plane. Ammonium cations are embedded between the heteropolyhedral layers. According to the thermodynamic and NMR measurements supported by the first-principles calculations, NH4VPO4OH presents a rare case of Haldane spin system with spin S=1 based on V3+ ions. © 2023 Wiley-VCH GmbH.
