Reactions of chloride iron(II) clathrochelates with aliphatic amines: an unexpected influence of the nature of the amine and solvent on the reaction products

The interaction of the reactive di- and hexachloride clathrochelate iron(II) precursors with primary and secondary aliphatic amines of different nature in a wide range of donor and acceptor solvents has been studied. The partially functionalized aminic clathrochelates obtained have been characterized using elemental analysis, PD mass, IR, UV–Vis, 57Fe Mössbauer and 1H, 13C NMR spectra and crystallographically (Fe((C6H11NH)2Gm)(Cl2Gm)(BC6H5)2 · n-C5H12 and Fe((n-C4H9NH)ClGm)(Cl2Gm)2(BC6H5)2 complexes). The causes of an unexpected influence both amine and solvent nature on the product of reaction with chloride clathrochelate precursors have been discussed.
