Abstract

Abstract: Reduction of indium boryl precursors to give two‐ and three‐dimensional M−M bonded networks is influenced by the choice of supporting ligand. While the unprecedented nanoscale cluster [In68 (boryl)12 ] − (with an In12 @In44 @In12 (boryl)12 concentric structure), can be isolated from the potassium reduction of a bis(boryl)indium(III) chloride precursor, analogous reduction of the corresponding (benzamidinate)In III Br(boryl) system gives a near‐planar (and weakly aromatic) tetranuclear [In4 (boryl)4 ] 2− system. Abstract : Clusters à la carte : Reduction of indium boryl complexes to give 2D and 3D aggregates can be controlled by the choice of supporting ligand. The unprecedented nanoscale cluster In12 @In44 @In12 (boryl)12 (see picture) is isolated from the potassium reduction of a bis(boryl) precursor, while reduction of (amidinate)In III Br(boryl) gives a (weakly aromatic) planar tetranuclear [In4 (boryl)4 ] 2− system.
