摘要：

The reaction of [Ru-III(edta)(H2O)](-) (edta = ethylenediamine-N,N,N',N'-tetraacetate) with isonicotinamide (isna) was studied spectrophotometrically at different pH (6-10), isonicotinamide concentrations and ionic strengths. The pyridyl -N-co-ordinated complex [Ru(edta)(isna)](-) is stable at low pH (6.0). but undergoes intramolecular isomerisation at high pH (9.6) to yield the amido-N-co-ordinated [Ru(edta)(isna)](2-). Upon acidification, the amido-N-bonded species isomerises;back to the pyridyl-N-co-ordinated isomer.
