Properties of the transition metals
... The transition metal ions have partially filled ‘d’ orbitals which can accept electron pairs by dative coordinate bonding. These form complex ions which may be positive or negative depending on the ligands attached. The shape of the complex ions depends on the ligands, the oxidation state and type o ...

Modelling for Coordination Complexes: Structure
... unsophisticated compared to QM, MM can be a remarkably good way of modelling molecules, especially those based on carbon chemistry, because carbon behaves in clear, well-defined ways which are relatively simple to capture mathematically. For example, each carbon atom is connected to four, three or t ...
