All of the ions considered in Chap. 11 were those for which the ground state is orbitally nondegenerate. The deviations of the g factors from g e are adequately described by the use of second-order perturbation theory. In Chap. 12 we encounter examples in which the crystal field does not...
Bidentate Ligands Some ligands contain two atoms which can donate a pair of electrons, they are therefore able to form two bonds with the metal ion. These are described as bidentate ligands; examples of bidentate ligands are: 1,2-diaminoethane (en) ethanedioate ion bipyridyl (bipy) e.g [...

Both of the atoms can coordinate to a single metal center. In the complex [Co(en)3]3+,[Co(en)3]3+, there are three bidentate en ligands, and the coordination number of the cobalt(III) ion is six. The most common coordination numbers are two, four, and six, but examples ...

The accessible d orbitals also cause the large polarizability of chalcogenide ions, which in turn gives rise to large defect concentrations and broad homogeneity ranges of transition-metal chalcogenides, stabilizes structures in which the chalcogen has a polar environment (for instance layer, fibre, ...
