(Butoxymethylidene)dimethylazanium tetraphenylborate acetonitrile monosolvate

Abstract

In the title solvated salt, C7H16NO+·C24H20B−·C2H3N, the C—N bond lengths in the cation are 1.2831 (19), 1.467 (2) and 1.465 (2) Å, indicating double- and single-bond character, respectively. The C—O bond length of 1.2950 (18) Å shows a double-bond character, pointing towards charge delocalization within the NCO plane of the iminium ion. The two C atoms of then-butyl group are disordered over the two sites, with refined occupancy ratios of 0.890 (5):0.110 (5) and 0.888 (4):0.112 (4). In the crystal, C—H...π interactions occur between the methine H atom, H atoms of the –N(CH3)2and –CH2groups of the cation, and two of the phenyl rings of the tetraphenylborate anion. The latter interaction forms an aromatic pocket in which the cation is embedded. Thus, a two-dimensional pattern is created in theacplane.
