Ruthenium(II) complexes bearing carboxylato and 2-oxocarboxylato ligands

The syntheses of ruthenium(II) acetato and benzoato complexes [Ru(bdmpza/(O2CCH3)(PPh3)] (6) and [Ru(bdmpza/)-(O2CPh)(PPh3)] (7) [bdmpza = bis(3,5-dimethylpyrazol-1-yl)-acetate] are reported. The complexes 6 and 7 are synthesized in high yield from [Ru(bdmpza)Cl(PPh3)2] (1) and thallium acetate (2) or thallium benzoate (3). In a similar substitution reaction a benzoylformate complex [Ru(bdmpza){O2C-C(O)Ph}(PPh 3)] (8) is obtained from 1 and thallium benzoylformate (4). Reaction of 6 or 7 with benzoylformic acid also yields 8. In analogous reactions several 2-oxocarboxylato ruthenium(II) complexes [Ru(bdmpza){O2CC(O)R} (PPh3)] (9 R = CH2CH2CO2H, 10: R = Me, 11: R = Et) can be obtained. The low-spin ruthenium(II) complexes 8 to 11 exhibit a purple or brownish-red colour caused by MLCT transitions and thus a HOMO-LUMO gap which is almost identical to that of high-spin 2-oxoglutarate dependent iron oxygenases. 6 crystallises as a water adduct, 6·H 2O and 8 forms an acetonitrile adduct 12, Crystal structures of the water adduct 6.H2O and 8 were obtained.
