Abstract
In the title mol-ecule, C12H17NO2, the amide NH2 group is oriented toward the pent-yloxy substituent and an intra-molecular N-H⋯O hydrogen bond is formed with the pent-yloxy O atom. The benzene ring forms dihedral angles of 2.93 (2) and 5.60 (2)° with the amide group and the pent-yloxy group mean planes, respectively. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with their mol-ecular 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 inter-actions, forming a three-dimensional framework structure.
