Magnetic exchange coupling in a nearly linear iron(III)nickel(II)nickel(II)iron(III) complex
Abstract
The reaction of LFeIIICl3 with Ni2(Hdfmp)2(L = 1,4,7-trimethyl-1,4,7-triazacyclononane, H3dfmp = 2-hydroxy-5-methylbenzene-1,3-dicarbaldehyde dioxime) produces in the presence of triethylamine, acetate and tetrafluoroborate ions, the dark brown complex [L2Fe2(µ2-O2CMe)2(dfmp)2(MeOH)2Ni2](BF4)2 which is characterized by X-ray crystallography and magnetic susceptibility measurements and found to have a paramagnetic ground state.
