1,4‐Diarsinine‐1,4‐diide compound [(ADC Ph )As] 2 ( 5 ) (ADC Ph ={C(DippN)} 2 CPh, Dipp=2,6‐iPr 2 C 6 H 3 ) with a planar C 4 As 2 ring fused between two 1,3‐imidazole scaffolds has been isolated as a red crystalline solid. Compound 5 , formally comprising an 8π‐electron C 4 As 2 ring, is antiaromatic and undergoes 2e‐oxidation with AgOTf to form the 6π‐electron aromatic system [(ADC Ph )As] 2 (OTf) 2 ( 6 ).
