Experimental and DFT Study of Monensinate and Salinomycinate Complexes Containing {Fe₃(µ₃-O)}⁷⁺ Core.

ABSTRACT: Two trinuclear oxo-centred iron(III) coordination compounds of monensic and salinomycinic acids (HL) were synthesized and their spectral properties were studied using physicochemical/thermal methods (FT-IR, TG-DTA, TG-MS, EPR, Mössbauer spectroscopy, powder XRD) and elemental analysis. The data suggested the formation of [Fe₃(µ₃-O)L₃(OH)₄] and the probable complex structures were modelled using the DFT method. The computed spectral parameters of the optimized constructs were compared to the experimentally measured ones. In each complex, three metal centres were joined together at the axial position by a μ₃-O unit to form a {Fe₃O}⁷⁺ core. The antibiotics monoanions served as bidentate ligands through the carboxylat
