Abstract
A new Fe(II) succinate (1) was synthesized in an autogenous pressure by a hydrothermal reaction. The crystal structure was determined by single crystal X-ray diffraction analysis. The prepared Fe5(OH)2(C4H4O4)4 crystallizes in a monoclinic unit cell with the dimensions of a = 9.489(2)Å, b = 9.429(3, c = 12.487(2)Å, β=96.77(1)° and space group of P21/c (No. 14). The oxygens of succinate coordinate iron(II) with edge-sharing octahedra to form three dimensional network. The oxidation state iron has been confirmed by valence sum calculation as well as by the room temperature magnetic susceptibility. At room temperature Fe(II)(3d6) shows high spin state with paramagnetic behavior.
