ABSTRACT:
A new group of materials comprises intercalates of organometallic compounds in layered structures of water-insoluble salts comprised of a tetravalent 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 vanadates. Intercalation hosts are represented either by the formula M(H.sub.1-y A.sub.y XO.sub.4).sub.2.nH.sub.2 O or by the formula H.sub.1-y A.sub.y TO.sub.2 XO.sub.4.nH.sub.2 O, 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 transition metal to which from 2 to 6 ligands are bonded.
