摘要：

A new metastable layered titanium arsenate, isostructural with Ti2O3(H2PO4)(2) . 2H(2)O, has been synthesized by acid treatment of the framework compound NH4TiOAsO4 at ambient temperature. Based on elemental analysis, IR spectroscopy, X-ray diffraction and thermogravimetry the formula Ti2O3(H2AsO4)(2) . 2H(2)O 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.
