Abstract
New iron carboxylate complexes with a aliphatic diamine, 1,3-diaminopropane ( dap ), were obtained under various synthesis conditions: in the air, [Fe III 4 O 2 (Piv) 8 ( dap ) 2 ] ( 1, Piv is the pivalate anion), and in an inert atmosphere, [Fe II (Piv) 2 ( dap ) 2 ] ( 2 ). New iron carboxylate complexes with a aliphatic diamine, 1,3-diaminopropane ( dap ), were obtained under various synthesis conditions: in the air, [Fe III 4 O 2 (Piv) 8 ( dap ) 2 ] ( 1 , Piv is the pivalate anion), and in an inert atmosphere, [Fe II (Piv) 2 ( dap ) 2 ] ( 2 ). The structure of the compounds was determined by single crystal X-ray diffraction analysis. In mononuclear complex 2 , the iron center coordinates two carboxylate ligands and two chelate dap . In the tetranuclear complex 1 , the coordination environment of the metal ions is different, and only two ions coordinate the chelate dap . According to Mössbauer spectroscopy data, the Fe 3+ ions in 1 and Fe 2+ ion in 2 are in a high-spin state and in an octahedral environment of donor atoms. A DC magnetic susceptibility study and quantum-chemical analysis of intramolecular pathways using broken-symmetry density functional theory (DFT) showed that the magnetic exchange coupling between the Fe 3+ ions of the central Fe 2 (μ-O) 2 unit is weak (| J | ≤ 7 cm −1 ), while each of these ions is coupled by fairly strong antiferromagnetic exchange interactions with two other Fe 3+ ions ( J = −32.9/−43.2 cm −1 ). The thermal behavior of 1 and 2 was studied by simultaneous thermal analysis (STA).
