Conclusions

  1. 1.

    The photochemical processes in aqueous solutions of ethylenediaminedicyano complexes of platinum were studied. Under the action of visible light, the dibromo complex En(CN)2Br2Pt is reduced to a compound of Pt (II), whereas the dichloro complex En (CN)2Cl2Pt undergoes a reaction of photoactivation. The dihydroxo compound En(CN)2 (OH)2Pt is stable under these conditions.

     
  2. 2.

    The redox potentials of the system En(CN)2Pt + 2e=En(CN)2Pt + 2X, where X = Cl, Br, were measured. A dependence of the redox potential on the nature of the equatorial and axial acido ligands was detected.

     
  3. 3.

    A crystallooptical characterization of the complex compounds; En (CN)2 (OH)2Pt, En (CN)2Cl2Pt, En(CN)2Br2Pt was given.
