Wavellite is orthorhmbic,space group C2v9—Pc21n.Unit-cell a0=9.57,b0= 17.3,c0=6.98,Z=4 molecules.The structural formula of wavellite is Al3（OH）3（PO4）2·6H2O. On the basis of Patterson function,the crystal structure of wavellite was solved. By means of the Model and Fourier method the oxygen position was determined. The crystal structure of wavellite is constructed by continuously linked chains of AI—O octahedra,which have three different coordinations,linked top to top but inc- lining to either left or right.The chain is along c-axis.The chains are connected by P—O tetrahedra in two different ways constructing a three-dimensional loose framework. According to this result an interpretation of the main physical properties of this mineral was satisfactorily obtained.
