Zirconium Phosphite (3,3′,5,5′‐Tetramethylbiphenyl)diphosphonate, a Microporous, Layered, Inorganic–Organic Polymer

Abstract

Pores of uniform size are found in the title compound (a structural model is shown on the right), in which parallel layers of a zirconium phosphate are joined by biphenyl “pillars”. The structure of this polymer, which may have potential as a shape-selective catalyst or a molecular sieve, is reminiscent of the architecture of a Greek temple.
