A homoleptic rare-earth-metal tetramethylindate
The homoleptic complex La(InMe<sub>4</sub>)<sub>3</sub> is obtained from the respective aluminium congener La(AlMe<sub>4</sub>)<sub>3</sub><i>via</i> a donor-assisted tetramethylaluminate/tetramethylindate exchange protocol. Compound La(InMe<sub>4</sub>)<sub>3</sub> exhibits interesting thermal lability as well as distinct cluster formation like La<sub>4</sub>In<sub>7</sub>(C)(CH)<sub>2</sub>(CH<sub>2</sub>)<sub>2</sub>(CH<sub>3</sub>)<sub>19</sub> and La<sub>5</sub>In<sub>9</sub>(CH)<sub>6</sub>(CH<sub>3</sub>)<sub>24</sub> upon addition of an excess of donor or thermal treatment. The neutral potentially tridentate ligand Me<sub>3</sub>TACN (1,4,7-trimethyl-1,4,7-triazacyclononane) is used to investigate donor-triggered intermediates. Compound La(InMe<sub>4</sub>)<sub>3</sub> is the first crystallographically characterized homoleptic rare-earth-metal tetramethylindate and may readily be used as a precursor for follow-up chemistry distinct from La(AlMe<sub>4</sub>)<sub>3</sub> and La(GaMe<sub>4</sub>)<sub>3</sub>.
