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.

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.
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.
