Ionic ligands
WebLigands are ions or neutral molecules that bond to a central metal atom or ion. Ligands act as Lewis bases (electron pair donors), and the central atom acts as a Lewis acid … Web18 jan. 2024 · This surface passivation strategy avoids the use of ionic ligands for the surface passivation of PNCs in polymer matrices, and we expect related surface chemistry to promote the performance enhancement of diverse PNCs–polymer composites for LEDs and other optoelectronic applications.

The results have shown that … WebP is also found here which is higher in energy. This means the two term symbol states are 4F and 4P. In the effect of the ligand field the term symbols split. The 4P and the 4F have orbital splitting energy of 15B, this is explained later on. So there are possible electron configurations in a strong ligand field case.
