Gmelin: Ruthenium Compounds

1. What mixed complexes exist with both water and halide ions as ligands?
2. What mixed complexes exist with both ammonia and halide ions?
3. How many oxidation states of Ru exist as halides or complexes with halide ions? Give examples.
4. What oxidation states of Ru are known as cyano complexes?
5. What appears to be the maximum number of pyridine molecules which can coordinate to Ru? Give examples.

Beilstein:

Identify the assigned compounds as index compounds, substitutional derivatives, or functional derivatives. Give Beilstein reference for main work and as many supplements as available.
