The reaction of 1-aminoadamantane hydrochloride and divalent metal chloride in concentrated hydrochloric acid medium yields two unusual complexes containing protonated 1-aminoadamantane, (C10H18N)1+2[ZnCl4]2− (1), (C10H18N)1+2[MnCl4(H2O)2]2− (2a) and (C10H18N)1+2[MnCl4(D2O)2]2− (2b). Their crystal structures have been determined by X-ray crystallography. Both complexes contain molecular network of (C10H18N)+ cations and divalent metal chloride polyhedral anions (Mn and Zn site symmetry 2/m). Dielectric constants of both two organic–inorganic hybrid salts were measured at different temperatures and frequencies. Different structures lead to large discrepancy in the dielectric property measurements. In addition, thermal analysis of complex 2 was studied.
Two novel organic–inorganic compounds (C10H18N)1+2[ZnCl4]2− (1) and (C10H18N)1+2[MnCl4(H2O)2]2− (2) were prepared. Compound 1 displays 1D chain structure, compound 2 displays 2D layer structure cross-linked by hydrogen bondings. Different structures lead to large discrepancy in the frequency dependence of the dielectric constant measurements.Figure optionsDownload as PowerPoint slide
