[5] In collaboration with William D. Phillips he exploited NMR for study of dynamic processes in inorganic fluoride compounds.

[9] In addition to the polyhedral boranes, the program explored pi-allyl, fluoroalkyl, and boron hydride complexes of the transition metals.

In 1979, Muetterties moved to the University of California, Berkeley, where he continued research in homogeneous catalysis and cluster chemistry.

[13] Muetterties helped establish the American Chemical Society journals Inorganic Chemistry and Organometallics.

He also edited books on boron chemistry and transition-metal hydrides and wrote reviews on complexes with unusual coordination numbers.
