Artykuł
Two mononuclear iron complexes with the quinoline-2-carboxylate ion (quin-2-c ion) have been obtained by the reaction of iron powder with quinoline-2-carboxylic acid in dichloromethane. The compounds [Fe(quin-2-c)2] (1), [Fe(quin-2-c)2(H2O)2] · 2CH2Cl2 (2) and [Fe(quin-2-c)2(H2O)2] · 2EtOH · 2H2O (3) have been investigated by IR and UV–Vis spectroscopy, magnetic susceptibility and field-dependent magnetization measurements. The structure of 2 has been characterised by X-ray diffraction. The 2D bilayered frameworks of 2 and 3 are constructed by extensive hydrogen bonding interactions between water and the organic ligand coordinated to iron (II). The magnetic properties of 2 and 3 were interpreted on the basis of a spin Hamiltonian that included axial and rhombic crystal field components. The weak antiferromagnetic (2) and ferromagnetic (3) interactions are evident in the low temperature data and possibly occur via strong hydrogen bonds.
