Magnetic and dielectric properties of (CHAn)2MCl4 and (An)2MCl4, where M=Cu or Mn, CHAn=4-cyclohexyl analinium and An=analinium

Abstract The magnetic susceptibility χ M and the relative permittivity e r ′ for (CHAn) 2 MnCl 4 , (An) 2 MnCl 4 , (CHAn) 2 CuCl 4 and (An) 2 CuCl 4 , where CHAn=4-cyclohexyl analinium and AN=analinium ions have been studied in the temperature range of 80–400 K. The results showed antiferromagnetic character for the Mn-compounds and ferromagnetic character for Cu-compounds. The plots of e r ′– T and χ M – T showed some breaks attributed to dynamic disordering of the organic chains. The results were correlated and discussed in view of the composition as well as the structure of the compounds.
