ABSTRACT OF THE DISCLOSURE A new composition of matter comprising the re- action product of a mixed oxide having layers of corner linked octahedra and tetrahedra and a Lewis base. The reaction product forms a layered compound of the formula LXMOM'O4 where MOM'O4 is a mixed oxide selected from the group consisting of VOPO4, VOSO4, VOAsO4, VOMoO4, NbOPO4, NbOAsO4, TaOPO4 and MoOPO4, x is from about 0.1 to 1.0 and L is a Lewis base containing nitrogen or oxygen electron donor and is selected from the group consisting of 5-mem- bered heterocyclic amines, 6-membered heterocyclic amines, amine oxides, triorganophosphates, phosphine oxides and sulfoxides. The layered compounds are characterized in that L is covalently bound to a metal atom in the MOM'O4 layer.
