Hydrothermal synthesis and structure characterization of a new 3D vanadium hydrogen phosphite with 14-ring channels: (C5N2H14)[VO(H2O)]3(HPO3)4·H2O

Synthesis and structural characterization of two cobalt phosphites: 1-D (H3NC6H4NH3)Co(HPO3)2 and 2-D (NH4)2Co2(HPo3)3

“…When the MO 6 octahedra have been displayed in the structure to extend the inorganic framework, the presence of MO 6 unit will definitely facilitate the building of high dimensional framework. For example, compound 2 and some vanadium, [14] iron, [20] manganese, [30] or bimetal phosphates [12] are 2-D or 3-D structures that contain MO 6 octahedra.…”

“…These properties usually lead to difficulty in mimicking a zeolitetype structure, but can lead to the possibility of new structural morphology and interesting magnetic properties [3][4][5][6][7][8]. Recently, the HPO 3 group has been investigated as a possible replacement for the tetrahedral HPO 4 unit with great success [9][10][11][12][13][14]. It is interesting to note that some zinc phosphites are isostructural to the corresponding zinc mono hydrogen phosphates, whereas others exhibit novel structures [15][16][17][18][19].…”

Extra‐Large‐Pore Zeolites: Bridging the Gap between Micro and Mesoporous Structures

“…A series of microporous zinc phosphites with 16R pores has been synthesized,26–29 including FJ‐1428 which has interesting magnetic properties. Vanadium, cobalt, and zinc phosphites with channels made of 14R, 16R, 18R, 24R, and 26R have recently been reported 30–33. For example, the open framework of ZnHPO‐CJ1 is made up of strictly alternating ZnO 4 tetrahedra and HPO 3 pseudo‐pyramids forming parallel 24R and 8R channels extending along the crystallographic c axis.…”

Amino acid template-synthesis and characterization of three-dimensional metal phosphate/phosphite networks

“…It is found that the replacement of tetrahedral phosphate groups PO 4 by pyramidal phosphite units HPO 3 can reduce the M-O-P connectivity, leading open framework structures [11,12]. Indeed, 16-ring and 24-ring zinc phosphites with novel open-framework structures and compositions have been successfully prepared [13,14].…”

Indeed, 16-ring and 24-ring zinc phosphites with novel open-framework structures and compositions have been successfully prepared [13,14].With respect to the synthetic methods, the organic agents have been employed as template to synthesize novel metal phosphates [15][16][17]. The organic entity is regarded as the key factor in promoting the formation of new types of inorganic networks.…”
