摘要

Examples of chemical reactions that occur in the solid state without disruption of crystalline order are quite rare. The most prevalent among these are photochemical reactions, absorption/desorption of solvents from porous materials, or changes in coordination polymers. There are very few examples of single-crystal-to-single-crystal reactions of mono-molecular species being reported and even fewer examples of such transformations of organometallic compounds. Notable exceptions include the recent elegant reports by van Koten, Brookhart, and McKeown, which describe single-crystal-to-single-crystal transformations in which the coordination environment around a transition metal changes. These transformations are of significant interest in terms of crystal engineering, chemical sensing, and materials science in general.
