摘要：

The crystals of 1:1 complex of 1,2-bis(dimethylaminomethyl)benzene with HClO4 were studied using X-ray diffraction and FT-IR spectroscopy. The space group is Cmc2(1) with a = 11.679(2), b = 13.129(3), c = 9.980(1) and Z = 4. The NHN+ intramolecular hydrogen bond is crystallographically symmetric. The N ... N distance is 2.689(8) Angstrom and the N ... H ... N angle 123(9)degrees. The perchlorate anion is highly disordered. The IR spectrum of the crystals shows a continuous absorption indicating very high polarizability of the intramolecular hydrogen bond. (C) 1998 Elsevier Science B.V.
