Abstract: Photocrystallography is a rapidly developing technique that enables the full three-dimensional structure of a molecule in a metastable or excited state to be elucidated when a single crystal of the complex is photoactivated by visible or UV light.[1] Pioneering work in the areas of both molecular and macromolecular photocrystallography has allowed the crystallographic characterization of species with microsecond and sub-microsecond lifetimes.[2, 3] Of equal importance are the detailed studies on the identification and stabilization of metastable species[4, 5] because of potential photorefractive applications, including data storage and optical switching.[6] This area has been pioneered by Coppens et al., and they, and others, have now successfully determined the structures of a number of metastable species including several transitionmetal– nitrosyl, –nitro, and –SO2 complexes.[7–9]
