Manipulating Magnetism: Ru Paddlewheels Devoid of Axial Interactions.
Variable-temperature magnetic and structural data of two pairs of diruthenium isomers, one pair having an axial ligand and the formula Ru(DArF)Cl (where DArF is the anion of a diarylformamidine isomer and Ar = p-anisyl or m-anisyl) and the other one being essentially identical but devoid of axial li...

Box 30012, College Station, Texas 77842-3012, United States Department of Chemistry, University of Texas at El Paso, El Paso, Texas 79968, United States su: Ruthenium compounds Molecular structure of isomers Magnetism Density functional theory Ligands (Chemistry) Molecular orbitals sug: subj: Ruthenium compounds Molecular structure of isomers Magnetism Density functional theory Ligands (Chemistry) Molecular orbitals ab: Variable-temperature magnetic and structural data of two pairs of diruthenium isomers, one pair having an axial ligand and the formula Ru(DArF)Cl (where DArF is the anion of a diarylformamidine isomer and Ar = p-anisyl or m-anisyl) and the other one being essentially identical but devoid of axial ligands and having the formula [Ru(DArF)]BF, show that the axial ligand has a significant effect on the electronic structure of the diruthenium unit. Variable temperature crystallographic and magnetic data as well as density functional theory calculations unequivocally demonstrate the occurrence of π interactions between the p orbitals of the chlorine ligand and the π* orbitals in the Ru units. The magnetic and structural data are consistent with the existence of combined ligand σ/metal σ and ligand pπ/metal-d/π interactions. Electron paramagnetic resonance data show unambiguously that the unpaired electrons are in metal-based molecular orbitals. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2014 holdings: @attributes: islocal: N |
