Abstract

The combination of anhydrous SnCl4 with 18-crown-6 in aqueous conditions results in formation of the non-hydrolysed product [cis-SnCl4(H2O)2] · 18-crown-6 · 2H2O. The X-ray crystal structure shows extensive intermolecular hydrogen bonding involving the cis-octahedral SnCl4(H2O)2 units, the uncoordinated water molecules and the crown ether. Similarly, [2,2,2]cryptand reacts with an aqueous solution formed by adding anhydrous GaCl3 to slightly acidic water, affording [[2,2,2]cryptand + 2H+][GaCl4]2.Treatment of anhydrous SnCl4 with 18-crown-6 in aqueous conditions results in formation of the non-hydrolysed product [cis-SnCl4(H2O)2.18-crown-6.2H2O. Similarly, [2,2,2]cryptand reacts with anhydrous GaCl3 in slightly acidic water, yielding [[2,2,2]cryptand + 2H+][GaCl4]2. Addition of the macrocyclic species in each case affords hydrolytic stability towards the metal halide.
