Disclosed are a class of compositions, and methods of preparing them, which compositions are comprised of inorganic oxides and organic bases. The compositions have layered structures and are represented by the formula ZaHbMc[An-1BnO3n+1] where Z is an organic base having a conjugate acid with a pKa value greater than about 3, H is hydrogen, M is a monovalent cation, O<a</=2, c<1, and b+c=1; A is a mono-, di-, or trivalent cation, B is a transition metal, n is an integer from 3 to 7.
