Megjegyzések:	Complex forming capabilities of [(?6-p-cymene)Ru(H2O)3]2+ with aminohydroxamates (2-amino-N-hydroxyacetamide (?-alahaH), 3-amino-N-hydroxypropanamide (?-alahaH) and 4-amino-N-hydroxybutanamide?(?-abhaH)) having the primary amino group in different chelatable position to the hydroxamic function were studied by pH-potentiometry, NMR and MS methods. Formation of stable [O,O] and mixed [O,O][N,N] chelated mono- and dinuclear species is detected in partially slow with ?-alahaH and ?-alahaH or in fast processes with ?-abhaH and the formation constants of the complexes present in aqueous solution are reported. Synthesis, spectral (NMR, IR) and ESI mass spectrometric characterization of novel dinuclear ?-alaninehydroximato complexes containing the half-sandwich type Ru(II) core is described. The crystal and molecular structure of [{(?6-p-cymene)Ru}2(?2-?-alahaH?1)(H2O)Br]Br?H2O (1) and [{(?6-p-cymene)Ru}2(?2-?-alahaH?1)(H2O)Cl]BF4?H2O (2) was determined by single crystal X-ray diffraction method. In the complexes one half-sandwich core is coordinated by a hydroxamate [O,O] chelate while the other one by [Namino,Nhydroxamate] fashion of the bridging ligand. In both cases the remaining coordination sites of one of the Ru cores are taken by a halide ion whiles the other one by a water molecule. Reaction of 2 with 9-methylguanine indicates the N7 coordination of this simple DNA model. Complexes 1 and 2 were tested for their in vitro cytotoxicity using human-derived cancer cell lines (A2780, MCF-7, SKOV-3, HCT116, HeLa) and showed no anti-proliferative activity in the micromolar concentration range.
