Synthesis and X‐ray crystal structure investigations of the complexes of a proton sponge with selected inorganic acids: Crystal structure of DMAN.HI complex

A series of ionic complexes of 1,8–bis(dimethylamino)naphthalene with selected inorganic acids such as HCl, HBr, HI, HSCN and HBF₄ were synthesised and thoroughly investigated by means of powder diffractometry and analytical methods. The crystallographic data for these compounds as well as the results of the structure solution by powder diffraction methods of the 1,8–bis(dimethylamino)naphthalene.HI complex, which crystallizes in the monoclinic system, S.G. P2₁/c (14), a=7.999(2)Å, b=23.053(3)Å, c=7.948(1)Å, β=99.63°, R_F=17.1%, R_wp=15.5%, are discussed and presented in this work. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
