Abstract

Reaction of [Mn(salophen)Cl] {salophen²⁻ = o-phenylenediamine bis(salicylidenaminato)} with a tricyano Fe(III) precursor complex, [Fe(bbp)(CN)₃]²⁻ {H₂bbp = bis(2-benzimidazolyl)pyridine}, affords a dinuclear cyano-bridged heterometallic Mn^III-(μ-NC)-Fe^III fragment in the complex salt [Mn(salophen)(H₂O)₂][Mn(salophen)(H₂O)(μ-NC)Fe(bbp)(CN)₂]·4H₂O (1). The title compound shows field-induced slow relaxation of magnetization below 2.8 K. Possibility of a protonation induced metal-to-metal electron transfer (MMET) process in the parent complex is probed by UV-visible, electrochemical, and electron spin resonance studies.
