Boron Clusters

May 2004
Vol. 81 No. 5
p. 768
Abstract
The May featured molecules are discussed in the Viewpoints article "Boron Clusters Come of Age". 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.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
