    The chemistry of interactions of 2-(2,6-diisopropylphenylaminomethylene)­indole ligand (<b>1</b>) with europium and ytterbium amides is described. Reaction of 2-(2,6-diisopropylphenylaminomethylene)­indole 2-(2,6-<i>i</i>-Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>NHCH<sub>2</sub>)­C<sub>8</sub>H<sub>5</sub>NH (<b>1</b>) with europium amide [(Me<sub>3</sub>Si)<sub>2</sub>N]<sub>3</sub>Eu<sup>III</sup>(μ-Cl)­Li­(THF)<sub>3</sub> afforded a novel europium­(II) complex formulated as {[μ-η<sup>6</sup>:η<sup>1</sup>:η<sup>1</sup>-2-(2,6-<i>i</i>-Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>NCH)­C<sub>8</sub>H<sub>5</sub>N]­Eu­[2-(2,6-<i>i</i>-Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>NCH)­C<sub>8</sub>H<sub>5</sub>N]}<sub>2</sub> (<b>2</b>), having a bridged indolyl ligand in the novel μ-η<sup>6</sup>:η<sup>1</sup>:η<sup>1</sup> hapticities with the reduction of europium­(III) to europium­(II) and the oxidation of amino to imino group.
