摘要：

In this paper we report the hydrothermal synthesis and characterisation of a new ethylenediammonium intercalated vanadyl phosphate, (H3NCH2CH2NH3)(0.5) [V0.324+V0.685+O2PO4P(OH)(2)(0.44)]. The phase purity of the solid was established using powder X-ray diffraction, single crystal X-ray diffraction, TGA, DTA, FTIR, UV-Vis and magnetic susceptibility measurements. Crystal data: orthorhombic,Pnma,a = 90289,b = 8.8962 andc = 15.9813 & ANGS;,V = 1283.7 & ANGS;(3),Z = 8. The structure contains layers made of VO5 square pyramids and PO4 tetrahedra; adjacent layers are connected through disordered tetrahedral PO2(OH)(2) units. Ethylenediammonium cations occupy cavities in between the layers.
