The abstraction of the silylium ion is seen from the ruthenium complex shown below.

In this case, the ruthenium complex acts as both photosensitizer and catalyst.

As mentioned above, some ruthenium complexes are able to oxidize water under solar light irradiation.

Structural control is easier than for ruthenium complexes due to the square planar structure of the platinum complex.

The fluorescence of some ruthenium complexes is quenched by oxygen, which has led to their use as optode sensors for oxygen.

Some ruthenium complexes absorb light throughout the visible spectrum and are being actively researched in various, potential, solar energy technologies.

This can be observed with the ruthenium complex below:

The rate of ligand exchange for ruthenium complexes is relatively slow in comparison with other transition metal complexes.

For this reason ruthenium complexes are able to take advantage of the body's ability to efficiently transport and uptake of iron.

The ruthenium complexes can be transported by binding to serum albumin and transferrin proteins.
