The first quasi‐binary acetonitriletriide Sr 3 [C 2 N] 2 has been synthesised and characterised. The nearly colourless crystals were obtained from the reaction of Sr metal, graphite, and elemental N 2 , generated by decomposition of Sr(N 3 ) 2 , in a sealed Ni ampoule with the aid of an alkali metal flux. The structure of this compound was analysed via single‐crystal X‐ray diffraction and the identity of the [C 2 N] 3− anion was confirmed by Raman spectroscopy and further investigated by quantum‐chemical methods. Computed interatomic distances within the [C 2 N] 3− anion strikingly match the obtained experimental data.
