A seven-coordinate manganese(II) complex with the tripodal tetradentate ligand tris(N methyl benzimidazol-2-ylmethyl)amine (Mentb) with composition [Mn(Mentb)(alpha methacrylate)(DMF)]-(ClO4) (DMF) was synthesized and characterized by elemental analysis electrical conductivity and IR and UV/Vis spectral measurements The crystal structure of the complex has been determined by single-crystal X-ray diffraction The Mn-II cation is bonded to a Mentb ligand an alpha-methacrylate ligand and a DMF molecule through four N atoms and three O atoms resulting in a seven coordinate geometry Cyclovoltammograms of the complex indicate a quasireversible Mn3+/Mn2+ couple The X band EPR spectrum of the complex exhibits a six-line manganese hyperfine pattern with g = 2 A = 91 and confirms that the material is high-spin Mn(II)
