C₅ and C₇ intra­molecular hydrogen bonds stabilize the structure of N-pyrazinoyl-gabapentin (Pyr-Gpn-OH)

In the title N-protected derivative of gabapentin (Gpn), the mol­ecular conformation is stabilized by intra­molecular five- (C₅) and seven-membered (C₇) hydrogen-bonded rings. The packing of the mol­ecules reveals O-H...O and C-H...N inter­molecular hydrogen bonds, together with [pi]-[pi] inter­actions.
