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 ... WebSep 7, 2024 · Theoretically, you cannot predict a priori whether a compound is high- or low-spin. For some reason, a lot of people seem to think that it depends only on the ligand and that it is possible to unambiguously use the position of the ligand in the spectrochemical series to figure out whether a complex is high- or low-spin.

Die Begriffe High Spin und Low Spin beziehen sich auf Koordinationskomplexe. Diese werden als Spinzustande von Komplexen bezeichnet.

WebThe other is called low-spin because it contains only two unpaired electrons. The same problem occurs with octahedral d 5, d 6, and d 7 complexes. For octahedral d 8, d 9, and d 10 complexes, there is only one way to write satisfactory configurations. As a result, we have to worry about high-spin versus low-spin octahedral complexes only when ...
