alkali in not given formation on heating of K2(PtCl4) with glycine; alkaline soln.;; trans-:cis-compound = 1:5;;

sodium hydroxide in water NaOH soln. was added to equimolar soln. of Pt-complex and glycine to maintained the pH at 3-4 for several hours, insol. ppt. was formed; detected by IR spectra;

perchloric acid; water in water heating glycine complex with 2-15 equiv. HClO4 (water-bath, 1 h), filtration off of cis-chelate, addn. of thiourea to filtrate; washing of cis-chelate (cold water, alcohol, ether), drying (105°C); yield decreasing with increasing acidity;

water in water heating glycine complex with 2-15 equiv. HNO3 or H2SO4 (water-bath, 1 h); washing of pptd. cis-chelate (cold water, alcohol, ether), drying (105°C);

in water heating with aq. KCl-soln.; reaction mechanism discussed; examination of the reaction-products depending on KCl-concn.;;
