ResumoThe crystals of the 1,8-bis(dimethylaminomethyl)naphthalene (DMAMN) monoperchlorate were grown from ethanol. The space group of the crystal is Pcab. The unit cell parameters are a = 11.032(3) Å, b = 12.201(4) Å, c = 25.572(6) Å, Z = 8. The NHN+ intramolecular hydrogen bonding distance is 2.675(5) Å and the NHN angle is 167(4)°. The proton is shifted towards the N(1) nitrogen atom: rN(1)−H = 1.18(4) Å while rH⋯N(2) = 1.51(4) Å. The IR absorption spectrum shows broad protonic bands at about 2000 cm−1 and 600 cm−1 which correlate with the length and asymmetry of the NHN bridge.
