Abstract

Isomeric complexes of platinum, which contain two non-innocent ligands are reported. The built-in coordination asymmetry in the ligands makes it possible to separate two different positional isomers. Results from X-ray crystallography is used to invoke the popular structure oxidation state correlation in these complexes. The redox processes are discussed and interpreted with the help of UV-vis–NIR and EPR spectroelectrochemistry.
