Complexes 1(R Me, Et) are accessible both thermally and photochemically. The central As 6 ring is a regular hexagon with bond lengths between those of As‐As single and double bonds. The 1 H NMR signals of the cyclopentadienyl Me groups are found at δ ≈ 0; this can be regarded as evidence of a ring‐current effect of hexaarsabenzene.
