Outer-sphere ligand to ligand charge transfer of metal complexes
Abstract
The electronic spectra of the salts [NiII(tim)]2+[MII(mnt)2]2–(tim = 2,3,9,10-tetramethyl-1,4,8,11-tetra-azacyclo-tetradeca-1,3,8,10-tetraene, H2mnt = 1,2-dicyano-1,2-ethylenedithiol, M2+= Ni2+, Pd2+, Pt2+) are dominated by an intense absorption band which is assigned to an outer-sphere ligand charge transfer transition from the complex anion to the cation.
