Abstract

The reactions of [Pt(dipic)Cl] (where H2dipic = pyridine-2,6-dicarboxylic acid) with 1-methylimidazole, ethylenediamine and nicotinic acid were studied at 40°C in dimethylformamide medium spectrophotometrically. The successive entry of two 1- methylimidazole molecules through initial chloride ion replacement followed by carboxylate ring opening process was further verified through intermediate product isolation. Nicotinic acid shows only the chloride substitution reaction. Bidentate ethylenediamine ligand gets chelated with the platinum(II) complex through slow chloride replacement and rapid ring opening process. All the products have been isolated and characterised through 1H NMR spectra.
