Abstract
Phenylphosphonic acid reacts by a metathesis reaction in a liquid medium with tetravalent zirconium ions, yielding layered crystalline to amorphous inorganic polymers having the empirical formula Zr(O.sub.3 PC.sub.6 H.sub.5).sub.2. One use for the compound is as a sorbent for small quantities of organic materials in aqueous solutions.
