Crystal structure of 2-pentyloxybenzamide

In the title molecule, C₁₂H₁₇NO₂, the amide NH2 group is oriented toward the pentyloxy substituent and an intramolecular N-H⋯O hydrogen bond is formed with the pentyloxy O atom. The benzene ring forms dihedral angles of 2.93(2) and 5.60(2)° with the amide group and the pentyloxy group mean planes, respectively. In the crystal, molecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with their molecular planes parallel, but at an offset of 0.45(1)Å to each other. These dimers are ordered into two types of symmetry-related columns extended along the a axis, with the mean plane of one set of dimers in a column approximately parallel to (121) and the other in a column approximately parallel to (1-21). The two planes form a dihedral angle of 85.31(2)°, and are linked via C-H⋯O hydrogen bonds and C-H⋯π interactions, forming a three-dimensional framework structure.
