Abstract

Abstract Inorganic compounds which contain pendant organic functional groups are prepared by the reaction of an acid of the formula [(HO) 2 OZO x ] k R, in which Z is a pentavalent metal, X is 0 or 1, k is 1 or 2, and R is an acyclic organo group, with a tetravalent metal ion. The compounds are insoluble in the reaction medium, exist in a layered crystalline to amorphous form, and have the formula M(O 3 ZO x R) n , in which M is the tetravalent metal and n is 1 or 2. One use for the compounds is as selective sorbents.
