Crystal structure of 2-pentyl­oxybenzamide

In the title mol­ecule, C(12)H(17)NO(2), the amide NH(2) 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.
