Heptamethylenediamine, C₇H₁₈N₂, molecules in the crystal structure are orientated parallel to the a axis and aggregate side to side in successive layers parallel to the bc plane. The bonds within the saturated chain show small variations in their length. Two weak intermolecular N-H...N hydrogen bridges occur between the molecules of successive layers.
