Bis(acetylacetonato)ruthenium Complexes of Noninnocent 1,2-Dioxolene Ligands: Qualitatively Different Bonding in Relation to Monoimino and Diimino Analogues
Original language description
Coordination compounds [Ru(acac)(2)(Q)] (acac = acetylacetonate; Q = o-benzoquinone) were prepared as complexes 1 (Q = o-benzoquinone), 2 (Q = 3-methoxy-o-benzoquinone), 3 (Q = 4-methyl-o-benzoquinone), and 4 (Q = 3,5-di-tert-butyl-o-benzoquinone). The structures of 1 and 2 were determined to reveal a Ru(III)/o-benzosemiquinone formulation, supported by analysis of experimental data (spectroscopy, magnetism of 1) and by DFT calculations. The S = 1 ground state calculated for 1 stands in contrast to thespin-paired analogues with arylimino-o-benzosemiquinonato and diimino-o-benzoquinone ligands. The close contacts of about 5.3 angstrom possible between semiquinone O atoms of different molecules in the crystal allow for intermolecular spin-spin interactions and an overall complex magnetic behavior. One quasireversible oxidation and two reversible one-electron reductions yielded the corresponding molecular ions, which were characterized by UV-visible-NIR and EPR spectroelectrochemistry in
