The Quasi-Binary Acetonitriletriide Sr [C N].

The first quasi-binary acetonitriletriide Sr [C N] has been synthesised and characterised. The nearly colourless crystals were obtained from the reaction of Sr metal, graphite, and elemental N , generated by decomposition of Sr(N ) , 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 N] anion was confirmed by Raman spectroscopy and further investigated by quantum-chemical methods. Computed interatomic distances within the [C N] anion strikingly match the obtained experimental data.
