Are the homoatomic ring anions P 6 4− and As 6 4− really planar and 10π aromatic outside of the binary alkali‐metal compounds? With the crystal structure of {Rb[18]crown‐6)} 2 Rb 2 As 6 ⋅6 NH 3 (see structure of the {Rb 4 As 6 } core; Rb green, As red) and the electron localization function, an attempt is made to clarify the nature of the chemical bond in these pnictides.
