Abstract
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 EQU Z.sub.a H.sub.b M.sub.c [A.sub.n-1 B.sub.n O.sub.3n+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.ltoreq.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.
