[K(2,2,2-crypt)]2[As7]·THF, 1 (2,2,2-crypt = 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane) is the first well characterized seven-atom radical anion of group 15. UV-Vis spectroscopy confirms the presence and electronic structure of [As7]2−. Cyclic voltammetry in DMF solution shows the As73−/As72− redox couple as a one-electron reversible process. Theoretical investigations explore the bonding and properties of compound 1.
