Relationships between geometries adopted by compounds, MLn, with different coordination numbers are developed and stereochemical changes in coordination compounds are analysed in terms of these relationships. The atom-atom interaction model (AAIM) view of molecular geometry in covalent species MLn is used to quantify the discussion where required. The AAIM emphasises the importance of both ML bond and LL interaction energies.
