Crystal structure of tert-butyl-N-phenylcarbonitrilium tetrachloridoaluminate

Abstract

In the title compound, (C11H14N)[AlCl4], the nitrilium (systematic name: 2,2-dimethyl-N-phenylpropanenitrilium) ion adopts a slightly distorted linear configuration [C—N[triple-bond]C = 178.87 (16) and N[triple-bond]C—C = 179.13 (17)°]. In the crystal, while there are no intermolecular hydrogen bonds, pairs of nitrilium ions are linked through π–π interactions [inter–centroid distance = 3.8091 (13) Å].
