WebJan 14, 2024 · Step 3: Each of the ligands had one bond to Pt, thus each is a 2-electron donor. The ligands combined contribute a total of 8 electrons. Step 4: Adding the 8 electrons from Pt(II) and the 8 electrons from the ligands gives a total electron count of 16.

WebIn coordination chemistry, hapticity is the coordination of a ligand to a metal center via an uninterrupted and contiguous series of atoms. [1] The hapticity of a ligand is described with the Greek letter η ('eta'). For example, η 2 describes a ligand that coordinates through 2 contiguous atoms. In general the η-notation only applies when ... Webthe complex after removal of the ligands as closed shell species. If you adopt a neutral counting procedure you will need to switch to charged counting to assess the oxidation …
Webb) I expect bent NO is in ionic counting way a 2 e X − ligand (in covalent counting (=neutral ligand method) a 1e donor). 3. Question: Total valence electron number. I remember: When we go from linear to bent the VE number decreases with -2, therefore I expect: a) linear goes along with N O X +, therefore: 10 + 6 + 2 = 18 VE. WebUse at least one of cach metal and ligand listed. Complexes must be neutral. Do not use more than 2 metal centers. Clearly show your electron counting. Ligands are shown …
WebAug 12, 2024 · But in any case, the way in which we "count" the electrons from ligands depends on the ligand type.
