Mixed-component layered tetravalent metal phosphonates/phosphates as precursors for microporous materials

Syntheses, characterization and electrical property of a new silver diphosphonate with zeolite-like framework and three-dimensional silver interactions: [Ag4(O3PCH2CH2PO3)]

“…The structure of 1 is obviously different from the common pillar-like structures of metal organodiphosphonates in following two aspects [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]: (1) In the structure 1 there is a threedimensional Ag-O with one-dimensional channels, while there are two-dimensional metal-oxygen layers in pillar-like structure. (2) Organodiphosphonate groups are inclused in the channel, but in common pillar-like structure the organodiphosphnate groups lie between two metal-oxygen layer.…”

“…Particularly, metal organodiphosphonates are very important in preparing meso/microporous materials [5][6][7][8][9] because the open frameworks can be adjusted through modifying lengths and shapes of the organic units. Generally, metal organodiphosphonates are pillar-like structures, such as Cr 2+ [10], Co 2+ [11,12], Cu 2+ [11][12][13][14], Zn 2+ [11,[15][16][17], Al 3+ [18], Ga 3+ [19], Ln 3+ [20], Ti 4+ [21,22], Zr 4+ [23][24][25][26][27] and Th 4+ [28]. However, as far as we know, there are few metal organodiphosphonates with zeolite-like structures in previous work.…”

Synthesis, characterization and intercalation property of layered zirconium benzylamino-N,N-dimethylphosphonate phosphate materials

“…Organic derivatives of a-zirconium phosphate (Zr(HPO 4 ) 2 Á H 2 O) were synthesized by direct reaction of tetravalent zirconium ions with organophosphoric or phosphonic acids in 1978, this method had been applied to preparation of layered compounds with different properties and functionalities [5][6][7]. In recent years, we and several research groups have reported a variety of hybrid zirconium phosphonate phosphates Zr(HPO 4 ) 2Àx (O 3 P-G) x Á nH 2 O (x = 0-2, G: organic groups) such as zirconium sulphophenylphosphonate phosphate Zr(HPO 4 [14], these zirconium phosphonate phosphate materials have been applied in heterogeneous catalysis.…”

Direct Synthesis of Functional Zeolitic Materials

“…The first microporous inorganic-organic polymers reported were zirconium-phosphite-diphosphonate materials, formed by zirconium phosphate layers pillared by organic groups [73][74][75]. However, the first description of full three-dimensional inorganic framework containing organic groups was described by Maeda et al [76].…”
