(2024). [Fe(µ2-OH)6]3- Linked Fe3O Triads: Mössbauer Evidence for Trigonal µ3-O2- or µ3-OH- Groups in Bridged versus Unbridged Complexes.. Molecules. 29. 13.https://mro.massey.ac.nz/handle/10179/70219The syntheses, coordination chemistry, and Mössbauer spectroscopy of hepta-iron(III) complexes using derivatised salicylaldoxime ligands from two categories; namely, 'single-headed' (H2L) and 'double-headed' (H4L) salicylaldoximes are described. All compounds presented here share a [Fe3-µ3-O] core in which the iron(III) ions are µ3-hydroxo-bridged in the complex C1 and µ3-oxo-bridged in C2 and C3. Each compound consists of 2 × [Fe3-µ3-O] triads that are linked via a central [Fe(µ2-OH)6]3- ion. In addition to the charge balance and microanalytical evidence, Mössbauer measurements support the fact that the triads in C1 are µ3-OH bridged and are µ3-O bridged in C2 and C3.(c) 2024 The Author/sCC BY 4.0https://creativecommons.org/licenses/by/4.0/Mössbauercoordination chemistryiron clusterJournal article10.3390/molecules291332181420-3049journal-articlehttps://www.ncbi.nlm.nih.gov/pubmed/389991703218molecules29133218
