Ferro- and ferri-magnetism in oximato-bridged MIIICuII chains (M = Mn and Fe). A molecular based ferromagnet with Tc= 9 K: [MnIIICuII-bis(1,2-cyclohexanedioneoximato)(acetato)(H2O)2]
Abstract
The study of the magnetic properties of the compounds [MIIICuII(L)2(MeCO2)(H2O)2], M = Mn and L = dimethylglyoximato (dmg)1 or 1,2-cyclohexanedioneoximato (chd)2 and M = Fe and L = dmg 3, shows that 1 is a metamagnetic compound, 2 is a bulk ferromagnet with Tc= 9 K and 3 orders antiferromagnetically at 7.5 K.
