Expectation and surprise in group 13 organometallics: molecular vs. polymeric aggregation of Me2Ga and Me2In norcamphor oximates

Abstract

Whereas (meso)-[(norcamphor oximato)GaMe2]2 (1) exhibits the dimeric M2O2N2 motif favoured by organo group 13 metal oximates, the Me2In derivative [{(meso)-[(norcamphor oximato)InMe2]2}2] (2) aggregates distinctly different with the In atoms adopting coordination number (CN) = 5; compound 2 is the first oximato-based chain-like coordination polymer in group 13 organometallics; it comprises alternating M2O2N2 and M2O2 ring dimers interconnected via two types of a fifth dative bond (O→In and N→In) to yield the new {M4O4N4} motif; the calculated energetics of the heteroatom rings involved in 1 and 2 confirm the diverging aggregational behaviour of Ga and In.
