A seven-coordinate FeIII compound: [Fe{O(CH2CO2)2}(H2O) 2(NO3)]. Preparation, structure and magnetic properties

A seven-coordinate FeIII complex, [Fe(oda)(H2O)2(NO3)], was obtained after dissolving Fe(NO3)3 · 9H2O in an aqueous solution of oxydiacetic acid (H2oda) at room temperature. In the solid state, the FeIII center adopts a pentagonal bipyramid geometry with an {FeO7} core formed by a tridentate oda2- a...
