Abstract

The rotational diffusion time of ruthenium (II)-bis(2,2'-bipyridine) (2,2'-biquinoleine) has been measured in polar solvents of different viscosity. The rotational dynamics can be explained in terms of the Stokes—Einstein—Debye hydrodynamics theory under stick boundary condition by considering the rotating body as a prolate spheroid enclosing the complex. This overestimates the intrinsic molecular volume by a factor of 1.5. The difference can be accounted for by solvent molecules intercalated in the interligand space and stabilized by electrostatic interaction with the charge of the metal atom.
