Abstract:
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) 4 Li 3 Fe(OPh) 3 (O 2 C 6 H 4 )Cl] 2 ( 1 ), [{(thf) 3 Li 3 Fe(OPh) 5 Cl} 3 ] n ( 2 ), and [(thf) 3 Li 3 Fe(OPh) 6 ] 2 ( 3 ), have been synthesized and characterized by single‐crystal X‐ray diffraction. While compounds 1 and 3 were synthesized by an oxidative substitution reaction, compound 2 was directly obtained from the Fe III salt. These compounds are accessible by both synthetic pathways. Additionally, in compound 1 , the phenoxy ligand was catalytically oxidized to ortho ‐catechol, which was incorporated into the structure of 1 as a ligand that coordinates strongly to iron. All compounds feature the Fe III ion with a trigonal, bipyramidal environment, with coordination number 5.
