• Ruthenium(III) and platinum(IV) form 1:2 (metal:ligand) complexes with acenaphthenequinone mono(thiosemicarbazone) (AQTS). The complexes are soluble in 70% <I>N</I>,<I>N</I>-dimethylformamide (DMF). The reagent has been used for the spectrophotometric determination of Ru(III) and Pt(IV). The optimum ranges of concentration for the determination of Ru(III) and Pt(IV) are 2.02–7.09 and 2.83–11.6 ppm over the pH range 5.3–6.8 and 1.9–4.1, respectively. The Sandell sensitivities for the determination of Ru(III) and Pt(IV) are 0.01 and 0.016 μg cm<SUP>−2</SUP>, respectively. The determination has also been carried out in the presence of foreign ions.
