| Abstract: | 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. |
