(U.S. 191) ABSTRACT OF THE DISCLOSURE A new group of materials comprises intercalates of organometallic compounds in layered structures of water-insoluble salts comprised of a tetra- valent metal cation and an acid phosphate, arsenate or vanadate anion Related materials comprise intercalates of organometallic compounds in layered structures of uranyl and transuranyl phosphates, arsenates and vana- dates. Intercalation hosts are represented either by the formula M(Hl-yAyXO4)2.nH2O or by the formula Hl-yAyTO2XO4.nH2O, where M is at least one tetravalent cation selected from the group consisting of zirconium, titanium, hafnium, cerium, thorium, tin, lead and germanium, A is at least one monovalent cation selected from the group consisting of lithium, sodium, potassium, rubidium, cesium, ammonium and substituted ammonium, X is at least one element selected from the group consisting of phosphorus, arsenic and vanadium, T is at least one element selected from the group consisting of uranium and transuranic elements, "y" ranges from 0 to 1 and "n" ranges from 0 to 6. Intercalated guests comprise an organometallic cation with a tran- sition metal to which from 2 to 6 ligands are bonded. These new groups of materials are useful as catalysts or catalyst percursors, diffraction gratings and cation exchange materials.
