Redox mediated dimerisation of a <i>cyclo</i>-As<sub>8</sub> complex
Reduction as well as oxidation of the <i>cyclo</i>-As<sub>8</sub> complex [{Cp''Ta}<sub>2</sub>(μ,η<sup>2:2:2:2:1:1</sup>-As<sub>8</sub>)] (A, Cp'' = 1,3- <sup><i>t</i></sup> Bu<sub>2</sub>C<sub>5</sub>H<sub>3</sub>) are demonstrated to afford controlled dimerisation to unprecedented As<sub>16</sub> species. The dication [{Cp''Ta}<sub>4</sub>(μ<sub>4</sub>,η<sup>2:2:2:2:2:2:2:2:1:1:1:1</sup>-As<sub>16</sub>)]<sup>2+</sup> slowly disproportionates in solution, yielding the largest polyarsenide species in a molecular complex known to date.
