An organometallic sol-gel route to layered zinc phenylphosphonate and encapsulation studies with η6-(C6H6)Cr(CO)3

Phenylphosphonic acid reacts with diethylzinc in toluene/THF to give a white gel. The gel was dried in air at room temperature for 8 h to give the layered compound [ZnC6H5PO3]·H2O (1). This process represents a convenient non-aqueous organometallic sol-gel route to a layered metal phosphonate material. Zinc phenylphosphonate synthesized using the sol-gel method is identical to that prepared using the conventional aqueous precipitation technique as determined by IR spectroscopy, thermal gravimetric analysis and powder X-ray diffraction. η6-(C6H6)Cr(CO)3 can be incorporated into the gel during the condensation reaction.

Tailoring the photoluminescence properties of transition metal phosphonates

A series of phenylphosphonates, Zn1-xMnx(O 3PC6H5)·H2O, where x = 0, 0.005, 0.25, 0.5, 0.75 and 1.0, has been prepared and their photoluminescence responses studied. The presence of Mn in the sample results in a red emission, whilst when x = 0 the emission is green. Levels of Mn 6(m-O3PC6H 4CO2)2 has been prepared by hydrothermal reaction of Ag(NO3) and m-phosphonobenzoic acid. The material has a 1D channel structure in which the channels are lined with the phenyl groups. Ag6(m-O3PC6H4CO2) 2 shows a green luminescence response to laser excitation, whilst the related Zn material, Zn3(m-O3PC6H 4CO2)2, shows an unusual yellow emission.

Selected-control synthesis of metal phosphonate nanoparticles and nanorods

By surfactant-assisted methods, nanoscale Co(O3PC 6H5)·H2O species of different morphologies, namely, nanoparticles and nanorods, have been successfully synthesized and characterized. Upon removal of the organic

Coordinative intercalation of alkylamines into layered zinc phenylphosphonate. Crystal structures from X-ray powder diffraction data

Zinc phenylphosphonate monohydrate takes up 1 mol of amine when contacted with liquid primary alkylamines. The mechanism of intercalation involves replacement of the coordinated water molecule by the amine molecules. Although the composition of the intercalate Zn(O3PC6H5)(RNH2) is consistent with the analytical and spectroscopic data, there exist discrepancies in the observed interlayer d spacings of the intercalate with respect to that in the host compound. The d spacing for the propylamine intercalate is in fact smaller than that in zinc phenylphosphonate itself. In order to understand this feature specifically and to explain the mechanism of amine intercalation in metal phosphonates in general, we have determined the structures of the intercalates. The structures of Zn(O3PC6H5)(RNH2), R = -C3H9 (1), -C4H11 (2), -C5H13 (3), were solved ab initio from X-ray powder diffraction data and refined by Rietveld methods. All the compounds are isostructural, and they crystallize in the monoclinic space group P21/c with a = 13.978(3) ?, b = 8.791(2) ?, c = 9.691(2) ?, and β= 102.08(1)○ for 1, a = 14.698(4) ?, b = 8.957(3) ?, c = 9.712(3) ?, and β= 102.465(3)○ for 2, and a = 16.267(3) ?, b = 8.935(2) ?, c = 9.695(2) ?, and β= 102.32(1)○ for 3. The structures of these intercalates are new and are different from that of the host compound although all of them are layered. In the intercalate the zinc atoms are tetrahedrally coordinated as opposed to octahedral coordination in the host compound.

Intercalation of ammonia into zinc and cobalt phenylphosphonates

Zn(O3PC6H5)·H2O and Co(O3PC6H5)·H2O can be easily dehydrated to yield structures that are isomorphous with the corresponding monohydrate. The dehydration is reversible since both derivatives quickly reabsorb moisture from the atmosphere. The dehydration reaction leaves an open coordination site on the metal allowing both anhydrous zinc and cobalt phenylphosphonates to intercalate ammonia upon exposure to a flow of ammonia gas, as evidenced by FTIR, elemental analysis, and TGA data. Carbon dioxide, carbon monoxide, oxygen, propylamine, and ethylene were not similarly intercalated. Computer-simulated calculations indicate that intercalation of molecules larger than NH3 result in significant overlap of van der Waals surfaces between the intercalate and the phenyl rings.

Synthesis and structural characterization of a homologous series of divalent-metal phosphonates, MII(O3PR)·H2O and MII(HO3PR)2

Layered phosphonate salts of divalent metal ions (Mg, Mn, Zn, Ca, Cd) are precipitated by combining aqueous solutions of a phosphonic acid and a soluble metal salt. In this way compounds in the series M(O3CnH2n+1)·H2O (M = Mg, Mn, Zn, n = 1-12; M = Ca, Cd, n = 1-4), M(O3PC6H5)·H2O (M = Mg, Mn, Zn), Ca(HO3PC6H5)2, and Ca(HO3PCnH2n+1)2 (n ≥ 5) were prepared. These compounds are insoluble in water at pH 7 but dissolve in dilute acid solutions. A preliminary X-ray structure for Mn(O3PC6H5)·H2O, refined in the orthorhombic space group Pmn21 with Z = 2 and a = 5.734 (5), b = 14.33 (3), and c = 4.945 (4) A?, is reported. The structure consists of layers of Mn atoms coordinated octahedrally by five phosphonate oxygen atoms and one water molecule. Each phosphonate group coordinates four Mn atoms, making a cross-linked Mn-O network. The phenyl groups lie above and below these approximately planar networks and make van der Waals contacts between layers. Compounds in the M(O3PCnH2n+1)·H2O (M = Mg, Mn, Zn) and M(O3PC6H5)·H2O (M = Mg, Zn) series crystallize in Pmn21 with a = 5.61-5.74 and c = 4.78-4.82 A? and with b varying according to the size of the alkyl or phenyl group. A structural model for these compounds is discussed.
