A series of cobalt complexes containing the dianionic ligands X(CH2COO)22- (X = S, tda; or X = O, oda) is reported. The complexes [Co(tda)(bipy)(H2O)]·4H2O (2), which was characterised by X-ray crystallography, [Co(tda)(phen)(H2O)] (3), [Co(tda){(MeO)2bipy}(H2O)]·2H2O (4) and [Co(tda)(dpp)(H2O)]·2H2O (5) are obtained by reaction of the precursor complex [Co(tda)(H2O)]n (1a) with the bidentate N-donor ligands 2,2-bipyridine (bipy), o-phenanthroline (phen), 4,4-dimethoxy-2,2-bipyridine [(MeO)2bipy] and 2,3-bis(2-pyridyl)pyrazine (dpp), respectively...
