Abstract

Anion photoelectron spectroscopy and theoretical calculations are combined to probe the structures and chemical bonding of two boron-rich oxide clusters, B5O3 and B6O3, which are shown to be appropriately formulated as B2(BO)3 and B3(BO)3, respectively. The anion clusters are found to each possess a bridging η2-BO group, as well as two terminal BO groups and are analogs of B2H3 and B3H3. This finding advances the boronyl chemistry and helps establish the isolobal analogy between boron-rich oxide clusters and boranes.
