The Quasi‐Binary Acetonitriletriide Sr₃[C₂N]₂

Abstract

The first quasi‐binary acetonitriletriide Sr3[C2N]2 has been synthesised and characterised. The nearly colourless crystals were obtained from the reaction of Sr metal, graphite, and elemental N2, generated by decomposition of Sr(N3)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 [C2N]3− anion was confirmed by Raman spectroscopy and further investigated by quantum‐chemical methods. Computed interatomic distances within the [C2N]3− anion strikingly match the obtained experimental data.

Stabilization Of The CN35− Anion In Recoverable High‐pressure Ln3O2(CN3) (Ln=La, Eu, Gd, Tb, Ho, Yb) Oxoguanidinates

“…The most investigated classes are cyanides (CN − ) [1,2] and carbodiimides (NCN 2− ), [3–9] although more complex anions (i.e. dicyanamides, [10,11] tricyanomethanides, [12] and acetonitriletriide [13] ) are known. Inorganic cyanides have applications in gold mining, metal finishing, electroplating [14] and also can be used as reactants or/and catalysts in organic syntheses [15] .…”
