description

Abstract Two new azido derivatives of quadridentate Schiff base manganese(III) complexes have been synthesized and characterized structurally and magnetically. X-ray structure analysis revealed that both complexes viz. [Mn2(L1)2(N3)2] (1) and [Mn2(L2)2(N3)2] (2), where H2L1=N,N′-(1,1-dimethylethylene)-bis-(salicylaldiimine) and H2L2=bis(o-hydroxyacetophenone)-ethylenediimine exist as phenoxo-bridged dimer. The magnetic susceptibility of the complexes has been measured in the 5–300 K range. At room temperature the MnIII ions in complexes 1 and 2 possess an S=4 ground state. The global magnetic interaction in complex 1 is found to be ferromagnetic, while for complex 2 it is anti-ferromagnetic.
