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
报道了一系列含有双阴离子
