Description
Summary:© CSIRO 2014. Three thiacalix[4]arene polynuclear complexes have been prepared by literature methods for detailed magnetic investigation. The [Fe 3 O(L) 2 ] (LH 4 = thiacalix[4]arene) complex is found to exhibit interesting anti-ferromagnetic exchange coupling. Jahn-Teller distortion in [Cu 4 (L) 2 ] complex leads to strong anti-ferromagnetic coupling at low temperatures. The temperature-dependent susceptibility of the [(µ-H 2 O)Eu 2 (LH) 2 (DMF) 4 ] complex is well described by a ground state involving the thermal population of the lowest three excited states.
