An orthophosphoric hybrid material was successfully prepared by a hydrothermal reaction at 110C. A single crystal X-ray structure, thermal behavior, IR, and NMR spectroscopy investigations are given for a new organic cation bis dihydrogenomonophosphate C 7H 12N 2[H 2PO 4] 2.1/2H 2O. The latter has been synthesized hydrothermally using 2,4-diaminotoluene (DAT) and orthophosphoric acid. The atomic arrangement can be described as inorganic sheets alternating with inorganic-organic layers. The organic group C 7H 12N + 2 is located between inorganic groups to build multiple hydrogen bonds to ensure the three-dimensional cohesion network. The thermal behavior and IR, NMR and impedance spectroscopy studies are discussed for the powder samples of this compound. Supplemental materials are available for this article.
