Abstract

Four novel mononuclear tetrahedral cobalt(ii) complexes containing exocyclic mesoionic ligands of molecular formulae [Co^II(L₁)(X)₂(MeCN)] X = Cl (1) or Br (2) and [Co^II(L₂)(X)₂(MeCN)], X = Cl (3) or Br (4) have been reported. It is found that simple substitution of L₁ (O donor in 1 and 2) by L₂ (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.
