Rezumat

This paper reports on the synthesis of a new trinuclear homometalic mixed-valence iron carboxylate cluster with furan-2-carboxylic acid. The complex with the formula [Fe2IIIFeIIO(C4H3OCOO)6(H2O)3]∙0.5CH3CN·2.25H2O was characterized by X-ray analysis that revealed that the compound crystalizes in the triclinic centrosymmetric group P-1, with the following unit cell parameters: a= 10.2758(6) Å, b= 11.5991(9) Å, c= 19.7349(15) Å, α= 105.060(7)°, β= 94.216(6)°, γ= 101.662(6)°.
