Siderophore, II. Tetrazolylenolat- und Semicorrinat-Anionen als Chelatliganden für Eisen(II)-und Kupfer(II)-Ionen: Vom Molekül zum Kollektiv

摘要: Reaction of tetrazolyl enolate 2 (HL2) with Cu(II) acetate yields the 3D-coordination polymer 4 ([CuL22]n). structure which is unequivocally established by single-crystal X-ray diffraction. The formation understandable if or its considered as tridentate chelate ligand and an intermediate coordinatively unsaturated copper(II) building block 6 assumed. monomers are bidentate coordinating two CN groups, leads to linking coordinative saturation at center three-dimensional 4. Semicorrin 8 (HL4), however, reacts Fe(II) give exceptional mononuclear tetrahedral complex 10 (X-ray). EPR Mossbauer spectra discussed.
