Bridging of platinacycles by cis-azobenzenes: synthesis and photochemical study. Structure of the twisted inorganic Z-1,1,2,2-tetrasubstituted diazaethene ((Z)-1, 2-diphenyldiazaethene)bis(chloro(((dimethylamino)methyl)phenyl-C, N)platinum(II))

The photochemical synthesis and X-ray characterization of new complexes derived from the reaction of orthopalladated N, N-dimethylbenzylamine and azobenzene. The spectral and thermochroic properties of three complexes and the kinetics of thermal composition are also discussed. The behavior of cis-Azobenzene in reaction was notable in its role as a bridging, bidentate ligand. This resulted in two platinum centers in close proximity and platinum planes almost perpendicular to the plane of the N=N double bond.
