Abstract:
Post-spinel-type AB2O4 compounds are stable at higher pressures than spinel phases. These compounds have garnered much interest in geo- and materials science for their geochemical importance as well as potential application as high ionic conductors and materials with strongly correlated electrons. Here, large-volume high-pressure syntheses, structural features and properties of post-spinels are reviewed. Prospects are discussed for future searches for post-spinel-type phases by applying advanced large-volume high-pressure technology.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
