“…The cobalt Co(2) atom is octahedrally coordinated to five oxygen atoms and one nitrogen atom of the 1, 4‐butanediamine molecule. The Co–O bond lengths are in the range of 1.990(4)–2.193(3) Å and O–Co–O bond angles vary in the range of 103.02(15) to 117.46(15)°, which are in agreement with those reported in other cobalt phosphites 13–21. The selected bond lengths and angles, and atomic coordinates are given in Tables S1 and S2 (Supporting Information).…”

“…Since the first amino‐templated cobalt phosphite (C 2 H 10 N 2 )[Co 3 (HPO 3 ) 4 ] synthesized by T . Rojo ,13 various cobalt phosphites with zero‐dimensional (0D) cluster, one‐dimensional (1D) chain, two‐dimensional (2D) layer, and three‐dimensional (3D) framework structures have been synthesized under hydro/solvothermal conditions 14–21. The compound CoHPO‐CJ2 is particularly interesting owing to the extra‐large 18‐ring channels 17.…”

The three‐dimensional (3D) inorganic‐organic hybrid framework cobalt phosphite (C2H6N)[Co1.5(OH)(HPO3)] (CoHPO‐CJ10) was synthesized hydrothermally. Its structure is constructed by the connection of CoO6 octahedra, CoO5N octahedra, HPO3 pseudo‐pyramids, and 1,4‐butanediamine molecules. It exhibits a pillared‐layer structure with an unusual Co/P ratio of 3/2. The 1,4‐butanediamine molecule acts as a pillar to link the adjacent cobalt phosphite layers to form open framework. Interestingly, such structure contains infinite edge‐sharing connected Co–O–Co chains, that are rarely occurred in the structures of cobalt phosphates/phosphites. It was characterized by single‐crystal X‐ray diffraction, X‐ray powder diffraction (XRD), infrared (IR) spectra, UV/Vis spectroscopy, thermal gravimetric analyses (TGA), inductively coupled plasma (ICP), X‐ray photoelectron spectroscopy (XPS), and elemental analyses. It exhibits antiferromagnetic interaction.

Three new organically templated cobalt phosphites, [C 4 N 2 H 12 ][Co(HPO 3 ) 2 ] (1), [(C 4 N 2 H 12 ) 0.5 (C 2 NH 8 )][Co 2 (HPO 3 ) 3 ] (2) and [C 2 NH 8 ] 2 [Co 3 (HPO 3 ) 4 ] (3) have been synthesized under solvothermal conditions templated by piperazine. Single-crystal structure analysis reveals that compound 1 displays a one-dimensional (1D) chain-like structure, containing corner-shared fourmembered rings. In compound 2, the linkages between CoO 4 and HPO 3 units form an inorganic layer with 4-and 12-membered aperture, while in compound 3, corner-sharing CoO 4 and HPO 3 units give rise to a three-dimensional structure with 16-membered ring channels, in which organic amine cations reside. The presence of 4-membered rings and one-dimensional chain/ladder structures in all compounds shows that such units are vital for building up of higher dimensionality. The magnetic properties of the three compounds are also discussed.

“…Lately, using phosphite group to replace tetrahedral phosphate group to afford new metal phosphites have attracted great attention [19]. Lots of metal phosphites have been synthesized and characterized, such as zinc phosphites [20][21][22], vanadium phosphites [23][24][25][26], cobalt phosphites [27][28][29][30][31][32][33], manganese phosphites [34,35] and iron phosphites . Among these materials, iron phosphites occupied a considerable position because of its rich diversity of structures and special magnetic properties.…”

Three open-framework iron phosphites: Fe п 5 (NH 4) 2 (HPO 3) 6 (1), Fe п 2 Fe ш (NH 4)(HPO 3) 4 (2) and Fe ш 2 (HPO 3) 3 (3) have been synthesized under ionothermal conditions. How the different synthesis parameters, such as the gel concentrations, synthetic times, reaction temperatures and solvents affect the products have been monitored by using high-throughput approaches. Within each type of experiment, relevant products have been investigated. The optimal reaction conditions are obtained from a series of experiments by high-throughput approaches. All the structures are determined by single-crystal X-ray diffraction analysis and further characterized by PXRD, TGA and FTIR analyses. Magnetic study reveals that those three compounds show interesting magnetic behavior at low temperature.
