Abstract

In contrast to carbon and its heavier congeners, group 13 elements are rarely observed to catenate into linear chains. Here, we find that treatment of indium(I) iodide with a protonated N-xylyl β-diketiminate and a strong potassium base in tetrahydrofuran yields a hexa-indium chain. X-ray crystallography revealed one β-diketiminate ligand bound to each indium center with no bridging ligands supporting the five indium-indium single bonds. The terminal indium centers were capped with iodine. Electronic spectroscopy and computations on a model compound offer preliminary support for σ delocalization along the chain.
