Abstract

The characteristic feature of the title mol-ecule, C16H23NO4, is the syn configuration of the partially double amide C-N bond [C-N-C-O torsion angle = -14.8 (2)°]. The crystal packing is determined by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, which link the mol-ecules into a double-chain structure extending along [010].

Keywords: butanoic acid; crystal structure; hydrogen bonding; monosubstituted γ-amino acids.
