... electronic or spin populations are only a pointer of the atom's OS. We have most recently shown that the so-called effective atomic orbitals (eff-AO's) can be utilized, treating alpha and beta electrons separately, to derive the most appropriate atomic electron configurations for the atoms or molecu ...

ORDANOCHROMIUM CHEMISTRY SUPPORTED BY -DIIMINE LIGANDS
... This molecule is a low-valent, coordinatively unsaturated chromium synthon accommodating variable oxidation states of the metal. It isomerizes and reacts with various small molecules (e. g. alkenes, alkynes and arenes) to produce novel organometallic molecules. It also catalyzes the selective trimer ...

... Transition metal ions lose the s-orbital electrons before they lose the d orbital electrons. This happens because the energy of the (n-1)d orbital is significantly less than the ns electrons. Coordination compound: A complex ion and counterion with no net charge. Complex ion: Charged species consist ...
