Magnetic studies of metal ion coordination clusters encapsulated with thiacalixarene
MetadataShow full item record
© CSIRO 2014. Three thiacalixarene polynuclear complexes have been prepared by literature methods for detailed magnetic investigation. The [Fe 3 O(L) 2 ] (LH 4 = thiacalixarene) 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.

Complex Adaptive Systems and Conversation Analysis: A New Perspective for Consumer Behaviour Research?Whiteley, Jervis (2002)The research question for this study is “Can concepts from complex adaptive systems and conversation analysis be used to research consumer behaviour?" This is, primarily, a theoretical question. After a wide-ranging ...
