| Abstract: | Nature of the solvent plays a major role in the photochemical behaviour of cis- and trans-PtCl2(ethylene)(amine)] complexes. Dimeric compounds Pt2Cl4-(amine)2] are obtained on irradiation of these complexes in chloroform or diethyl ether. A non-stereospecific reaction of photosubstitution is observed in nitrile solvents. When methanol, dimethoxyethane or dimethylformamide are used as solvents, cis and trans complexes have a quite different photochemical behaviour, but in all of the cases, a photodegradation leading to ionic species PtCl3(ethylene)]? H+ amine and PtCl3(amine)]? H+ amine is the main reaction. |
