Single Crystal Growth of Sparingly Soluble Adducts of Lewis Acids with Bases
A method is described for growing single crystals from a solution where a base’s concentration is controlled so that an adduct to be grown is equilibrated with the solution. A slight difference in its solubilities at two different temperatures is responsible for their growth process. The technique is valuable for adducts which cannot readily be grown in other ways owing to their low solubilities.
