A Double Dose Of Crystal-To-Crystal Transformations
Examples of chemical reactions that occur in the solid state without disrupting the crystallinity of the original compound are rare, but Cathleen M. Crudden and coworkers of Queen’s University, in Kingston, Ontario, have discovered an unprecedented back-to-back example of such transformations (Angew. Chem. Int. Ed., DOI: 10.1002/anie.201103316). The chemists were exploring why electron-rich rhodium(I) N-heterocyclic carbene complexes resist oxidation to form rhodium(III) complexes. In one reaction they found that treating a dirhodium ethylene . . .
