Popis: Five complexes of formula [Ru(η6-C6H5CH2COOH)(XY)Cl]Cl/Na (XY = ethylenediamine (1), o-phenylenediamine (2), phenanthroline (3), and oxalato (4)) and [Ru(η6:κ1-C6H5CH2COO)(tmen)]Cl (tmen = N, N, N', N'-tetramethylethylenediamine, 5C) have been synthesized and fully characterized. Five new X-ray crystal structures ([Ru(η6-C6H5CH2COOH)(μ-Cl)Cl]2, 1, 3, 4, and 5C·PF6) have been determined, which are the first examples of ruthenium(II) structures with phenylacetic acid as arene ligand. Furthermore, 5C·PF6 is the first example of a five-membered tether ring with a Ru(η6:κ1-arene:O) bond. The tether ring in these complexes opens in acidic pH (
