(C(2)H(10)N(2))[Cr(HPO(3))F(3)]: The First Organically Templated Fluorochromium(III) Phosphite.

In recent years the search for new open-framework materials with transition metal elements has become the focus of much interest due to the potential application of these materials as absorbents, ion exchangers, solid-state electrolytes, and catalysts in heterogeneous catalysis.[1] Such applications are not possible with main group systems of tetrahedral framework zeolites. The syntheses of these materials usually involve organic templates, for example organic diamines, for generating large cavities and are performed under mild hydrothermal conditions to avoid the formation of dense phases. Microporous behavior has been successfully extended to the phosphate and arsenate systems of at least 14 elements of the periodic table, but examples dealing with chromium have not been reported.[1b,2] The pattern of behavior of these kinds of compounds is underpinned by the strength of the P O COMMUNICATIONS
