Synthesis, structural characterization and magnetic behaviour of a family of [Co2 IIILn2 III] butterfly compounds

We have successfully prepared and structurally characterized a family of butterfly-like [Co2 IIILn2 III] complexes where all magnetic properties are due to the Ln(iii) ions. The complexes with Ln = Tb(1), Dy(2), Ho(3), Er(4) and Yb(5) are iso-structural. An exception is the complex with Ln = Gd(6) w...
