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 [In <subscript>68</subscript> (boryl) <subscript>12</subscript> ] <superscript>-</superscript> (with an In <subscript>12</subscript> @In <subscript>44</subscript> @In <subscript>12</subscript> (boryl) <subscript>12</subscript> concentric structure), can be isolated from the potassium reduction of a bis(boryl)indium(III) chloride precursor, analogous reduction of the corresponding (benzamidinate)In <superscript>III</superscript> Br(boryl) system gives a near-planar (and weakly aromatic) tetranuclear [In <subscript>4</subscript> (boryl) <subscript>4</subscript> ] <superscript>2-</superscript> system.<br /> (© 2017 Wiley-VCH Verlag GmbH & Co.
