| Abstract: | The synthesis, structure, and magnetic properties of a tetrairon(III) complex Fe4(μ2-O)2Cl4(L)4]·0.5H2O (1, L = 2-methyl-8-hydroxyquinoline), which was prepared under solvothermal conditions and characterized by IR spectra, elemental analysis, TG, and single-crystal X-ray crystal diffraction, are presented. Each Fe center adopts a distorted trigonal bipyramid geometry and is coordinated with three oxygen atoms, one nitrogen atom, and one chlorine atom. Each 2-methyl-8-hydroxyquinoline is coordinated to two FeIII ions with μ2-η2:η1 coordination mode. The magnetic properties of the complex are dominated by antiferromagnetic exchange interactions. |
