Beside the system of oxidation numbers as used in " Stock nomenclature " for coordination compounds, and the lambda notation, as used in the IUPAC nomenclature of inorganic chemistry, " oxidation state " is a more clear indication of the electronic state of atoms in a molecule.

Coordination polymers contain the subclass coordination networks that are coordination compounds extending, through repeating coordination entities, in 1 dimension, but with cross-links between two or more individual chains, loops, or spiro-links, or a coordination compound extending through repeating coordination entities in 2 or 3 dimensions.
