A new metastable layered titanium arsenate, isostructural with Ti2O3(H2PO4)22H2O, has been synthesized by acid treatment of the framework compound NH4TiOAsO4at ambient temperature. Based on elemental analysis, IR spectroscopy, X-ray diffraction and thermogravimetry the formula Ti2O3(H2AsO4)22H2O was assigned to the novel compound. The layered nature of the compound was confirmed from amine intercalation and the ion exchange behavior towards alkali and alkaline earth metals.
