Heterotrinuclear [Fe2IIINiII]-µ3-oxo-cluster Based on Salicylic Acid. Synthesis, Structure and Physico-chemical Properties

Abstract

The reaction between iron and nickel salts with ammonium salicylate results in the formation of a new trinuclear heterometallic complex [hexa-µ2-salicylato-µ3-oxo-(methanol)(dimethylformamide) aquadiiron(III) nickel(II)] methanol dimethylformamide. The synthesized [Fe2NiO(SalH)6(CH3OH)(DMF)(H2O)]•DMF•CH3OH complex crystallizes in the monoclinic space group C2/c. The IR and Mössbauer spectra and thermal properties were studied.
