Abstract

Reaction between <i>nido</i>-6-HNB<sub>9</sub>H<sub>11</sub> (from[9-(MeNC)-<i>arachno</i>-6-HNB<sub>9</sub>H<sub>11</sub>] and [(η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>).IrCl<sub>2</sub>]<sub>2</sub> in the presence of N,N,N’,N’-tetramethylnaphthalene-1,8-diamine) gives [9-Cl-8-(η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>)-<i>nido</i>-8,7-IrNHB<sub>9</sub>H<sub>10</sub>] as a yellow crystalline solid in 40% yield. Crystals are triclinic, space group <i>P</i>1, <i>Z</i> = 2, with <i>a</i> = 825.5(1), <i>b</i> = 986.4(2), <i>c</i> = 1 158.7(2) pm, α = 95.12(1), β = 91.00(1), γ = 111.90(1)°. The molecular structure is based on an open-faced <i>nido</i> {IrNB<sub>9</sub>} eleven-vertex polyhedron with the iridium and nitrogen atoms in adjacent positions in the open face. Nuclear magnetic single and multiple resonance spectroscopy assigns the cluster <sup>11</sup>B and <sup>1</sup>H resonances, and suggests strong electronic similarities to the sulphur-containing analogue [9-Cl-8-(η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>)-<i>nido</i>-8,7-IrSB<sub>9</sub>H<sub>10</sub>].
