Four novel complexcs were obtained by reaoting H₂PtCl₆·6H₂O or Na₂PtCl₆ with 18 Crown-6 and 1, 7, 10, 16-tetraoxa-4, 13-diazacyclooctadecane in molar ratio of 1:2 and 1:1 respectively. The complexes arc stable and slightsoluble or unsoluble in common organic solvents. In hydrosilylation of unsaturated compounds the complexes show a high catalytic activity at 80℃ and can be recovered and reused for several times. The activity of the complexes are, however, lower than that of H₂PtCl₆ or Na₂PtCl₆ alone when the hydrosilylation is carried out at 40℃ or room temperature.
