Description
Julijan Sarcevic, Tobias Heitkemper, Niklas Mehner, Maximilian Kubis, and Christian P Sindlinger report a new boron and gallium cluster with a shape no one had made before. Their 2026 paper builds the cluster on a charged ring shaped ligand that holds two gallium atoms in a low, reactive state. The pair sits like an inverted sandwich, with the gallium atoms facing outward on both sides.
Early tests show the two gallium atoms talk to each other through the cluster and act as electron givers toward other metals and acids. Adding more of the free ring ligand oxidized the pair into a bent chain, the first of its kind for group 13 elements. The cluster can also release a single gallium ion, so it behaves as both a stable cage and a source of reactive parts.
