Hydrogen bonded assemblies of a cyclic trimeric hydroxy gallium(III) derivative: [{Me2Ga(µ-OH)}3·3H2O]2·18-crown-6
Abstract
Addition of hydrolysed trimethylgallium to an excess of 18-crown-6 in water affords an alkyl µ-hydroxo bridged Ga(III) trimer in solution (pH ca. 6) and the solid, isolated as the hydrogen bonded assembled supermolecule [{Me2Ga(µ-OH)}3·3H2O]2·18-crown-6.
