alpha- and beta-CuAlCl(4): Framework Construction Using Corner-Shared Tetrahedral Metal-Halide Building Blocks.

Rapid quenching of a melt of CuCl and AlCl(3) results in the formation of the metastable framework structure, beta-CuAlCl(4). The structure, determined by single-crystal X-ray crystallography (space group Pna2(1), a = 12.8388(5) Å, b = 7.

The Hydrogen-Bonded Framework of the First Anti-Zeotype: [{(H NEt ) } (CuCl )][AlCl ].

A two-coordinate cationic link between [CuCl ] tetrahedra by means of two inversion-related dialkylammonium cations yields the hydrogen-bonded A X anti-cristobalite framework [{(H NEt ) } (CuCl )] . This novel cationic framework is constructed around space-filling and templating [AlCl ] anions resulting in large pores (16.6×6.
