Abstract
Layered divalent metal pentavalent metallate, M(HAO.sub.4).sub.x (RAO.sub.3).sub.y (Z).sub.z wherein M is divalent metal, A is a pentavalent metal, e.g. phosphorus, R is a substituent group other than H or OH, e.g., phenyl, covalently bonded to A, x+y=1, y is greater than O, z ranges from 0 to 2, inclusive, and Z is an intercalated moiety is prepared by contacting a source of divalent metal with a substituted phosphonic acid-type compound under hydrothermal conditions.
