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