Ligand effects on the [Cu(PhO)(PhOH)]+ redox active complex.
Under gas phase conditions, the [Cu(PhO)(PhOH)](+) complex is composed of copper(I), a phenoxy radical bound via the oxygen atom, and a phenol bound via the aromatic ring. Effects of additional ligand coordination on the molecular and electronic structure of the complex [Cu(PhO)(PhOH)](+) are investigated by mass spectrometric and quantum chemical means for [Cu(PhO)L](+) (L = H(2)O, CH(3)OH, tetrahydrofuran, NH(3), pyridine, imidazole, 1,2-dimethoxyethylene, N,N,N',N'-tetramethylethylenediamine, pyrrole, and thiophene) and [Cu(PhO)(PhOH)L(n)](+) (L = H(2)O, NH(3), and 4-methylimidazole) models. The nature and number of additional ligands critically influences the spin distribution in the complex, which is sensitively reflected by the phenoxy CO stretching mode.
