Abstract in another language

The reaction of [FeL(MeOH)2] {where L is the tetra­dentate N2O2-coordinating Schiff base-like ligand (E,E)-diethyl 2,2'-[1,2-phenyl­enebis(nitrilo­methyl­idyne)]bis­(3-oxo­butanoate)(2-) and MeOH is methanol} with 3-amino­pyridine (3-apy) in methanol results in the formation of the octa­hedral complex (3-amino­pyridine-[kappa]N1){(E,E)-diethyl 2,2'-[1,2-phen­yl­ene­bis­(nitrilo­methyl­idyne)]bis­(3-oxobutanoato)(2-)-[kappa]4O3,N,N',O3'}(methanol-[kappa]O)iron(II), [Fe(C20H22N2O6)(C5H6N2)(CH4O)] or [FeL(3-apy)(MeOH)], in which the FeII ion is centered in an N3O3 coordination environment with two different axial ligands. This is the first example of an octa­hedral complex of this multidentate ligand type with two different axial ligands, and the title compound can be considered as a precursor for a new class of complexes with potential spin-crossover behavior. An infinite two-dimensional hydrogen-bond network is formed, involving the amine NH group, the methanol OH group and the carbonyl O atoms of the equatorial ligand. T-dependent susceptibility measurements revealed that the complex remains in the high-spin state over the entire temperature range investigated.
