摘要
Na4HP3O10. H2O crystallizes orthorhombic in space group Pbcn with a = 693.2(5) pm, b = 1203.3(4) pm, c = 1188.5(4) pm; Z = 4. The obtained X-ray diffraction data (9268 symmetrical independent reflections, R=0.047) allowed to locate and refine all the hydrogen atoms. The structure of Na4HP3O10. H2O contains alternating layers of triphosphate anions and sodium cations. The triphosphate ions have site symmetry Ct and are linked by strong oxygen-hydrogen bonds (244pm). The results of thermochemical analyses as well as the vibrational spectrum and data of P-31 MAS-NMR are submitted.
