An ionothermal synthesis study of transition metal phosphates using the ionic liquid 1-butyl-4-methylpyridinium hexafluorophosphate [C4mpy][PF6] yielded four new, different open framework manganese compounds, that is, K2Mn3(HPO4)2(PO3F)F2 (1), (NH4)2Mn3(HPO4)2(PO3F)F2 (2), KMn3(H2PO4)(HPO4)2F2 (3), and (NH4)Mn3(H2PO4)(PO3F)2F2 (4). The obtained products not only feature new framework topologies unprecedented in the family of phosphates but also interesting properties as the transition metal gives rise to both luminescent (rendering them potential nonrare earth containing red emitting phosphors) and unconventional magnetic properties governed by geometric frustrations. Aside from the structural analysis (powder and single-crystal X-ray diffraction, infrared spectroscopy), a variety of characterization methods (photoluminescence spectroscopy and magnetic measurements) were applied to study the material’s properties. Single crystal X-ray studies reveal that 1 (P21/c with a = 5.501(1), b = 14.203(3), c = 16.905(4) Å, β = 108.65(3)°, V = 1251.4 Å3, and Z = 4) and 2 (P2 1 /c with a = 5.587(1), b = 14.507(3), c = 17.364(3) Å, β = 108.75(3)°, V = 1332.6(5) Å3, and Z = 4) feature S-shaped 18-ring channels along [100], which are formed by trimer-Mn3O9F2 chains parallel to [100] and interconnecting PO3(OH) and PO3F tetrahedra. The structure of compounds 3 (C2/c with a = 20.307(4), b = 7.635(1), c = 7.834(2) Å, β = 103.26(3)°, V = 1182.2(4) Å3, and Z = 4) and 4 (C2/c with a = 20.402(4), b = 7.673(1), c = 7.845(2) Å, β = 103.56(3)°, V = 1193.8(4) Å3, and Z = 4) are characterized by layers, which are built of Mn3O8F4 octahedra trimers, with Kagomé topology parallel to the bc plane featuring 3,6-ring channels. The layers are stacked according to a sequence of AA i along the a axis. Taking into account the [P(2)O3(OH)/P(2)O3F] tetrahedra, the Kagomé layers are replenished to a Mn3O2(HPO4)/Mn3O2(PO3F) composition, which are interlinked by [P(1)O2(OH)2] forming 10-ring channels parallel to [001]. Charge compensation of the macroanions is achieved by K+ (1 and 3) and (NH4)+ (2 and 4) cations. At room temperature, compounds 1–4 demonstrate a reddish orange emission ascribed to the spin-forbidden 4T1g(4G) → 6A1g(6S) transition of the Mn2+ ions. Upon lowering the temperature to 77 K, the emission of each compound is red-shifted and becomes pure red. Compounds 1 and 2 contain spin trimers with a presumable doubled ground state. The intertrimer magnetic coupling is relatively weak, and small ferrimagnetic domains are possible in 1. The magnetic behavior of 3 and 4 can be considered as antiferromagnetic. This can be understood as their staircase Kagomé lattices are distorted, meaning that the intrinsic geometrical frustration is lifted.

“…Many research are concerned about the open‐framework materials in the past several decades, due to its fascinating structures and the widely potential applications in catalysis, absorption and proton conduction, etc . Phosphorus‐based metal oxide (MPO) are one of the most important inorganic materials, especially on the investigation of pseudo pyramidal phosphite group [HPO 3 ] 2– instead of tetrahedral phosphate group [PO 4 ] 3– as a basic building unit to combine the structure . To rich and complicate the structures of metal phosphites, many attempts have made it possible by using various ligands .…”

Two novel cobalt phosphite‐oxalates with different frameworks, which are isomeric and of stoichiometry Co(H2PO3)(C2O4)·(C2H8N) (1 and 2), were prepared under solvothermal conditions by in situ reactions. Single‐crystal X‐ray diffraction analysis reveals that 1 crystalilizes in the triclinic system space group P1 and 2 crystallizes in the monoclinic system space group P21/n. Compound 1 shows a 2D layered structure and 2 presents a 3D open‐framework. Both structures are constructed with zigzag cobalt oxalate chains and [H2PO3]– pseudopyramids. The solvent with different pH values and components plays an important role in the formation of the final structures of both compounds. Moreover, magnetic properties were also investigated.
