Back Cover: Double Single-Crystal-to-Single-Crystal Transformation and Small-Molecule Activation in Rhodium NHC Complexes (Angew. Chem. Int. Ed. 35/2011)
Chemical transformations that occur in single crystals without disruption of the crystal lattice are rare, particularly for organometallic complexes. C. Crudden and co-workers describe a dinitrogen–rhodium complex with an N-heterocyclic carbene in their Communication on page 8100 ff. that undergoes two back-to-back single-crystal-to-single-crystal transformations to O2 and CO complexes.
