The reaction of iron nitrate and nickel chloride with ammonium salicylate in the presence of methanol and dimethylformamide (DMF) results in the formation of a new trinuclear heterometallic complex [hexa- μ2-salicylato- μ3-oxo-(methanol) (dimethylformamide) aquadiiron(III) nickel(II)] methanol dimethylformamide. The complex crystallizes in the monoclinic space group C2/c and was structurally characterized by single crystal X-ray diffraction as [Fe2NiO(SalH)6(CH3OH)(DMF)(H2O)]·DMF·CH3OH, where SalH are monodeprotonated salicylic acid ions. The IR and Mössbauer spectra and thermal properties were studied. The parameters of the Mössbauer spectrum (δFe= 0.45 mm/s, ΔEQ= 1.086 mm/s, 300 K) suggest the high-spin state of the Fe3+ ions (S= 5/2). |
