Trinuclear carboxylate compound [Fe3O(CH3COO)6(h2o)3]2[PtCl6]× 8H2O has been studied by Mossbauer spectroscopy, magnetochemistry, thermal analysis and X-ray crystallography. Crystal data: monoclinic, space group P21/n, a = 10.505(2), b = 14.278(3), c = 19.885(4) A, b=96.00(3)0 and Z = 2. The final R-value is 0.027 for 4606 reflections with I ł 2s(I). The crystal consists of the complex [Fe3O(CH3COO)6(H2O3]+ cations, centrosymmetric [PtCl6]2- anions and water molecules. The [Fe3O(CH3COO)6(H2O)3]+ cation has the typical structure of a trinuclear iron (III) compound with m3-O bridge. All crystal components are connected via a system of hydrogen bonds into a 3D network. Mossbauer spectrum displays at room temperature a single quadrupole doublet with an isomer shift of 0.70 mm/s and quadrupole splitting of 0.48 mm/s, consistent with high-spin Fe(III). mcff per Fe atom (3.25 mB at 293 K and 2.23 mB at 120 K), indicate the antiferromagnetic coupling between the paramagnetic iron with J = -31 cm -1.
