Isolation of a novel singly oxo-bridged low-spin Fe(II) dimeric complex: Synthesis, crystal structure, and spectroscopic study
Redox reaction between [(phen)(4)Fe-2(Cl)(2)(mu-O)]Cl-2.4.5H(2)O (phen = 1,10-phenanthroline) and Mn(OH)(2).xH(2)O in water methanol solution at refluxing temperature under inert atmosphere gives a novel low-spin iron(II)-oxo complex [(phen)(4)Fe-2(Cl)(2)(mu-O)].4H(2)O (1) which has been characterised by IR, Mossbauer, electrochemical and magnetic studies. The crystal structure shows that complex 1 is a dinuclear single oxo-bridged Fe(II) species with distorted octahedral geometry.
