Boron Clusters May Featured Molecules The May featured molecules are discussed in the Viewpoints article “Boron Clusters Come of Age” on pages 657–672. The review paper by Russell N. Grimes on boron clusters reminds us both of the past impact that these interesting structures have had on the development of our understanding of cluster chemistry and on the future development of what one might refer to as “post-fullerene”

clusters. The wide range of structures found in this paper admirably illustrate the structural flexibility arising from clusters of a variety of symmetries and degrees of boron replacement with carbon and other atoms.
