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.

Keywords: Group 13 elements; boryl; gallium; indium; metal cluster.
