Synthesis and Characterization of a 1,2,4-Diazarsolide Anion
Cyclopentadienyl anions ([Cp]<sup>-</sup>) are pervasive ligands in coordination chemistry. In contrast, heavy-element derivatives of these ligands, particularly those that feature arsenic, are not as well developed. In this work, a new arsenic-based heterocycle with a structure analogous to [Cp]<sup>-</sup> is presented. Reaction of K<sub>3</sub>As<sub>7</sub> with benzyl azide (BnN<sub>3</sub>) leads to fragmentation of the [As<sub>7</sub>]<sup>3-</sup> core and C-H activation of two [BnN] units to give the five-membered arsenic heterocycle [As(NC(Ph))<sub>2</sub>]<sup>-</sup>. This arsenic heterocycle was studied by nuclear magnetic resonance and UV-vis spectroscopy, X-ray diffraction, and its electronic structure was investigated computationally.
