WebSep 2, 2015 · The high-spin state is the one according to Hund’s rule where electrons are filled into the five d orbitals one after the other. A low-spin state is any complex in which the Hund rule is not strictly observed, but some orbitals are filled with two electrons while others remain empty. Classic examples for high-spin complexes are, e.g. $\ce ... WebWhen iron (II) is bonded to certain ligands, however, the resulting compound may be diamagnetic because of the creation of a low-spin situation. If the ligands attached to the Fe (II) metal are strong-field ligands in an octahedral configuration, a low-spin situation is created in the d orbitals. All of the electrons are paired and, as a result ... darren tweed ballymena https://windhamspecialties.com
