Abstract

The crystal structure of the title compound, C(10)H(13)NO, displays an infinite one-dimensional network composed of primary amide molecules connected by N-H...O[double bond]C hydrogen bonds involving the anti NH amide H atoms, thus generating a C(4) motif. This network is additionally stabilized by a weak N-H...pi interaction between the syn-oriented amide H atom and the aromatic ring of a neighbouring molecule. The distance between the H atom and the ring centroid is 2.50 A. The amide group and the aryl moiety are nearly perpendicular, forming an intramolecular dihedral angle of 84.69 (6) degrees.
