Abstract: 2-{1-[(Pyrazin-2-ylformamido)methyl]cyclohexyl}acetic acid (Pyr-Gpn-OH), C14H19N3O3, is an N-protected derivative of gabapentin (Gpn). The compound crystallizes in the triclinic space group P\overline{1} and the molecular conformation is stabilized by intramolecular five- (C5) and seven-membered (C7) hydrogen-bonded rings. The packing of the molecules reveals intermolecular O-H...O and C-H...N hydrogen bonds, together with [pi]-[pi] interactions.

Formula: C14H19N3O3

Keywords: crystal structure; gabapentin; conformation; hydrogen bonding; [pi]-[pi] interactions.
