A new hope for crystallization

Recent work from Dan Li and co-workers, published in the March issue of Chem, reports the application of a cyclic trinuclear Ag^I pyrazolate complex (Ag₃Pz₃) as an adaptive crystallization agent for a series of difficult-to-crystallize organic molecules. Ag₃Pz₃ was also employed for the direct structural elucidation of organic compounds from mixtures in addition to natural products in crude extracts.
