A new hydrogen-bonded pseudo-dimer Mn(III) Schiff base complex. The synthesis, X-ray structure and spectroscopic studies

Abstract

A new hydrogen-bonded pseudo-dimer, [Mn(III)L1(CH3CH2OH)](2)(ClO4) (1) (L1 = N,N'-bis(2-hydroxy-1-naphthalidenato)-1,2-diaminopropane) has been synthesized and characterized by UV-vis, IR, elemental analysis and crystal structure analysis. The single crystal X-ray diffraction reveals that the structure affords an elongated octahedral MnN2O4 coordination environment, geometry with the four donor atoms of the tetradentate Schiff base in the equatorial plane and with two ethanol molecule in axial positions with Mn-O = 2.265(2) and 2.266(2) angstrom.
