Chérémond, Yvens Crochet, Aurélien Fromm, Katharina M. 2012-01-24 Heterobimetallic lithium–iron coordination compounds are interesting targets for several reasons: they can be used as precursors for mixed metal oxides, as catalysts, for example, for ring-opening polymerization reactions or to study oxidation/reduction processes. Finally their magnetic properties are also of interest. New heterobimetallic aryloxide complexes, namely [(thf)₄Li₃Fe(OPh)₃(O₂C₆H₄)Cl]₂ (<b>1</b>), [{(thf)₃Li₃Fe(OPh)₅Cl}₃]<em>_n</em> (<b>2</b>), and[(thf)₃Li₃Fe(OPh)₆]₂ (<b>3</b>), have been synthesized and characterized by single-crystal X-ray diffraction. While compounds <b>1</b> and <b>3</b> were synthesized by an oxidative substitution reaction, compound <b>2</b> was directly obtained from the Fe^III salt. These compounds are accessible by both synthetic pathways. Additionally, in compound <b>1</b>, the phenoxy ligand was catalytically oxidized to <em>ortho</em>-catechol, which was incorporated into the structure of <b>1</b> as a ligand that coordinates strongly to iron. All compounds feature the Fe^III ion with a trigonal, bipyramidal environment, with coordination number 5. application/pdf https://folia.unifr.ch/global/documents/302331 https://folia.unifr.ch/documents/302331/files/fro_scn.pdf https://folia.unifr.ch/documents/302331/files/fro_scn_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1002/ejic.201101054 info:eu-repo/semantics/openAccess License undefined European Journal of Inorganic Chemistry. - 2012, vol. 2012, no. 16, p. 2725-2730 Iron Lithium Aryloxides Oxide precursors Homogeneous catalysis info:eu-repo/classification/udc/54 Synthesis and characterization of new pentacoordinate iron-based aryloxide complexes http://purl.org/coar/resource_type/c_6501
