| Abstract: | A new linear trinuclear MnIII-MnII-MnIII complex 1 has been synthesized and characterized by elemental, spectral, X-ray and magnetic analysis. X-ray diffraction studies show that the central MnII ion is located at a crystallographic inversion center and is triply bridged to the terminal MnIII ions through one methoxide, one syn-syn carboxylate and one hydroxyl oxygen bridges with the short MnIII…MnII distance that is 3.047 Å. The intermolecular C-H…O, C-H…π and ring-metal interactions are observed in the hydrogen-bonded assembly of 1. Magnetic studies reveal that the mixed-valence complex 1 has S = 3/2 ground state with antiferromagnetic exchange interactions between MnII and MnIII ions. |
