Electronic Delocalization in Two and Three Dimensions: Differential Aggregation in Indium “Metalloid” Clusters
Reduction of indium boryl precursors to give two‐ and three‐dimensional M−M bonded networks is influenced by the choice of supporting ligand.

Zusammenfassung: | 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)InIIIBr(boryl) system gives a near‐planar (and weakly aromatic) tetranuclear [In4(boryl)4]2− system.
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)InIIIBr(boryl) gives a (weakly aromatic) planar tetranuclear [In4(boryl)4]2− system. |
