Description |
Four novel mononuclear tetrahedral cobalt(II) complexes containing exocyclic mesoionic ligands of molecular formulae [Co-II(L-1)(X)(2)(MeCN)] X = Cl (1) or Br (2) and [Co-II(L-2)(X)(2)(MeCN)], X = Cl (3) or Br (4) have been reported. It is found that simple substitution of L-1 (Odonor in 1 and 2) by L-2 (S donor in 3 and 4) results in switching of the single ion magnetic anisotropy parameter (D) from positive to negative, with a significant change in magnitude.
