New Architectures for Zirconium Polyphosphonates with a Tailor-Made Open-Framework Structure

The use of tetraphosphonic building blocks for the preparation of
inorganic−organic zirconium derivatives has led to the formation
of novel compounds with a modular structure. This is based on
the different connection of polymeric 1D inorganic units covalently
connected by organic groups. The different kinds of connections
generate two different open-framework structures. These structures
have been solved “ab initio” by powder X-ray diffraction data. Very
likely, the dimensions of the channels inside these structures may
be tuned by the right choice of the interlinking organic group.
