“…Work in our laboratories and others has dispelled the notion that these materials can only be formed as layered materials, with porous materials being reported that contain R groups such as -CH 2 4 and -CH 3 . 5 Many of the porous materials reported in the literature have a common feature.…”

“…In this respect, phosphonate anions containing carboxylate or carboxylic acid functional groups are ideally suited for the formation of porous materials, and a number of materials of this type, containing a variety of metals, have been reported in the literature. 3,[6][7][8][9][10][11][12][13] Of the phosphonocarboxylates reported, most contain carbon chains of two or more methylene units. A few, however, are based upon the phosphonoacetate anion, [O 3 PCH 2 CO 2 H] 2-.…”

“…It can exist in any one of four forms: the fully protonated uncharged molecule, monoanionic (where one phosphonate oxygen is deprotonated), dianionic (where one phosphonate and the carboxylate oxygens are deprotonated), and the fully deprotonated trianionic form. 14 To date, Zn, 3,9 Mn, 12,13 Al, 15 Fe, 16 Pb, 10,12 and Cu 9 derivatives of phosphonoacetic acid have been reported in the literature, which variously contain all three possible forms of the phosphonoacetate anion.…”

“…5 Many of the porous materials reported in the literature have a common feature. [1][2][3][4] Whereas the phosphonate anion contains a functional group that can act as a Lewis base, coordination to the metal atoms often occurs via this group in addition to coordination by the -PO 3 H n -(2-n) (n ) 0, 1, 2) group. This mode of coordination can lead to cross-linking of chains or lamellae to form 2D or 3D solids, or can occur entirely within discrete layers within a lamellar solid.…”

ABSTRACT:The syntheses and structural characterization of 1D, 2D, and 3D materials based on copper phosphonocarboxylate backbones are described. More specifically, the synthesis of materials from diethylphosphonoacetic acid (DEPAA) or the close variant hydroxyphosphonoacetic acid (HPAA) and water-soluble Cu 2+ salts has been studied. The initial synthesis involving copper acetate and DEPAA was carried out at 160°C under hydrothermal conditions and a Cu:P ratio of 1:1 resulted in the formation of a mixture of products with the same composition, Cu 1.5 (O 3 PCH 2 CO 2 ) · H 2 O. Compound 1, which is blue in color and crystallizes in the triclinic space group P1 j , has a layered structure. Compound 2, which is green in color and crystallizes in the monoclinic space group P2 1 /c, has a three-dimensional structure. Reduction of the reaction temperature to 140°C results in the exclusive formation of the R-phase (1), while an increase in the reaction temperature to 180°C yields a pure sample of 2. A Cu:P ratio of 2:3 in a reaction at 180°C yields a third, related phase, Cu(HO 3 PCH 2 CO 2 ) · H 2 O, 3, which is again triclinic but has a chain-like structure. Finally, reaction of copper chloride and HPAA in a Cu:P ratio of 1:1 at room temperature yields one-dimensional Cu(R,S-HO 3 PCH(OH)CO 2 )(H 2 O) 2 ] · H 2 O, 4, that incorporates both R and S HPAA stereoisomers. All materials were studied by single crystal X-ray crystallography, X-ray powder diffraction, TGA, FT-IR, and elemental analyses.

“…Attempts to synthesize porous zirconium phosphonates have been mainly based upon organically pillared biphosphonates or structurally modified biphosphonates with small spacer moieties. Relatively, the latter method gives more chance to obtain microporosity or mesoporosity [19][20][21]. According to Clearfield et al, the stacking of unequally sized layers could yield the pores.…”

Nanoporous metal phosphonates make up a growing family of organic–inorganic hybrid solids, which extends the scope of functional materials with potential in adsorption, ion exchange, catalysis, and sensing. Their attributes include thermal stability and the ability to incorporate functional organic and inorganic components accessible to adsorbates. The best established are those based on zirconium, comprising layered solids in which organic groups act as pillars between inorganic zirconium phosphate sheets. The porosity, which can be on the micro‐ or mesoscale, is engineered by design of the organic pillars and their number density and, while not ordered on the long range, can have a narrow distribution. Other pillared layered metal phosphonates are also known. More recent developments have yielded framework metal phosphonates with well‐defined permanent microporosity similar to that observed in zeolites, in the 0.3–1‐nm range, that demonstrate molecular sieving. Currently, the most promising solids of this kind include aluminum methylphosphonates and metal bisphosphonates, which can be described as metal–organic frameworks or MOFs. Another area of smaller, but developing interest is the preparation of metal phosphonates with ordered mesoporosity, in which a wide range of solids with relatively narrow distribution of pore sizes in the 3–15‐nm range is prepared by surfactant‐templated approaches. These have potential in the interaction with large molecules, including proteins.
