IMOD was developed at the Boulder Laboratory for 3-D Electron Microscopy of Cells.
2.
Written in the Enemark-Feltham notation, the d electron count is { CrNO } 5.
3.
It is important to remember that the d electron count is a formalism and describes some complexes better than others.
4.
Due to spin-orbit coupling between the d electrons, this state is split into a pair of energy levels.
5.
Thus for coordination complexes the standard electron configuration formalism is meaningless and the d electron count formalism is a suitable substitute.
6.
But referring to the formal oxidation state and d electron count can still be useful when trying to understand the chemistry.
7.
Using the neutral electron counting scheme, Cr has 6 d electrons and NO?has one electron for a total of 7.
8.
These properties are due to metallic bonding by delocalized d electrons, leading to cohesion which increases with the number of shared electrons.
9.
:: Even though Al doesn't have any d electrons, it " can " indeed use d orbitals to make bonds.
10.
The Jahn-Teller distortion is especially common in certain transition metal complexes; for example, copper ( II ) complexes with 9 d electrons.
