“…It was obvious that there was a little weight loss step at 460 , ℃ which was attributed to the thermal decomposition of the surfactant PEG-400 adsorbed by the sample. The result also showed that the temperature for dehydration of 2 4 . This is also confirmed by the IR spectra of the sample heated at 600 ℃ [ Figure 3(c)].…”

“…[11][12][13] Recently, Nenoff and co-workers 14 used a hydrothermal method to prepare a new layered twodimensional zincophosphate material, NaH(ZnPO 4 ) 2 . The phase consists of a two-dimensional network of ZnO 4 and PO 4 tetrahedra, linked through oxygen vertices, to form structures whose interlayers are occupied by charge-balancing cations. However, up to now, NaH(ZnPO 4 ) 2 was prepared in solution, 14 and little work on the preparation with a solid state reaction at low-heating temperatures has been reported.…”

“…However, up to now, NaH(ZnPO 4 ) 2 was prepared in solution, 14 and little work on the preparation with a solid state reaction at low-heating temperatures has been reported. Kowalak 13 and his co-workers synthesized zincophosphate sodalite by means of dry substrate grinding via the solid state reaction of Na 2 HPO 4 with zinc salt at room temperature, and obtained crystals of NaZnPO 4 •H 2 O with a sodalite (SOD) structure. The results suggested that the phase of layered NaH(ZnPO 4 ) 2 could be prepared via the solid state reaction with appropriate raw materials at an ambient temperature.…”

A simple and novel route for the synthesis of layered sodium hydrogen zinc phosphate, NaH(ZnPO 4 ) 2 , was studied, and the target product was obtained with Na 2 HPO 4 •12H 2 O and Zn(NO 3 ) 2 •6H 2 O as raw materials and polyethylene glycol-400 as a surfactant via a one step solid state reaction at 60 . The product was characterized with ℃ XRD, TG/DTG and FTIR. The experimental results showed that the NaH(ZnPO 4 ) 2 had only one major step of weight loss for dehydration of 2 4 HPO -into 2 7 P O 4-ions at around 500 , so ℃ it had enough thermal stability to use as heterogeneous catalyzer for organic reactions. The comparison experimental results suggested that aging temperature control the products of the synthesis, that is, the NaH(ZnPO 4 ) 2 was formed when the reaction mixture was aged at 60 ℃, and the α-Zn 3 (PO 4 ) 2 •4H 2 O was obtained when the reaction mixture was aged at room temperature.

“…Haussühl et al [44] investigated the Zn ↔ Mg substitution in hopeite ((Mg x Zn 1Ϫx ) 3 (PO 4 ) 2 · 4H 2 O) and showed that substantial amounts of octahedrally coordinated zinc can be replaced by magnesium. On the other hand, Bensalem et al [19] reported the existence of MgZn(HPO 4 ) 2 · H 2 O. From the similarities between the observed lattice parameters and those for Na 2 Zn(HPO 4 ) 2 · 4H 2 O [45] these authors assumed that both compounds should be closely related.…”

A phase analysis of an industrial filter cake residual based on X-ray powder diffraction data gave evidence for the existence of a previously unknown hydrous magnesium zinc phosphate. An optical investigation of the sample indicated the presence of milky white crystals (intergrown with polycrystalline rutile) with a maximum diameter of about 150 μm. Aided by an EDX-analysis, a single crystal diffraction study performed at Ϫ100°C proofed that the material represents a phase with composition Mg[ZnPO 4 (H 2 O)] 2 · 10H 2 O. Basic crystallographic data are as follows: monoclinic symmetry, space group P2 1 /c, a ϭ 10.702 (1), b ϭ 7.4740(9) Å , c ϭ 11.444(1) Å , β ϭ 104.09(1)°, V ϭ 887.8(2) Å 3 , Z ϭ 2, (R(ΗFΗ) ϭ 0.048). From a structural point of view the new compound is based on [ZnPO 4 (H 2 O)] Ϫ layers containing ZnO 3 (H 2 O)-and PO 4 -tetrahedra arranged at the vertices of a 4.8 2 net. The layers are parallel to (100) and alternate with sheets of isolated Mg(H 2 O) 6 2ϩ -octahedra and additional interstitial water molecules. Linkage between the tetrahedral and octahedral sheets is provided by hydrogen bonding. The topology and geometry of the tetrahedral layers are very similar to those observed in the minerals veszelyite, herderite and kipushite. According to the DTAmeasurements the present compound is stable up to 89°C, where dehydration to an amorphous product occurs.
