摘要：

The crystals of the 1,8-bis(dimethylaminomethyl)naphthalene (DMAMN) monoperchlorate were grown from ethanol. The space group of the crystals is Pcab. The unit cell parameters are a = 11.032(3) angstrom, b = 12.201(4) angstrom, c = 25.572(6) angstrom, Z = 8. The NHN+ intramolecular hydrogen bonding distance is 2.675(5) angstrom and the NHN angle is 167(4)-degrees. The proton is shifted towards the N(1) nitrogen atom: r(N(1)-H)) = 1.18(4) angstrom while r(H...N(2)) = 1.51(4) angstrom. 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.
