WebNov 5, 2024 · You should not be so concerned with whether the ligand is strong- or weak-field. That is only half of the story. After all, you are looking at a metal-ligand complex which can be high-spin or low-spin. Although the ligand plays an important part in determining that, the metal is equally important. See: chemistry.stackexchange.com/a/59171/16683 WebOct 17, 2024 · A quick-and-dirty rule (which means that it is correct most of the time but not always) is that weak ligands (iodide, bromide, hydroxide etc) are pi-donor ligands. The medium ligands (water, ammonia etc) are pi-neutral, and the strong ligands (cyanide, carbonyl, bipyridine, etc) are pi-acceptor. But this method is some kind of reversing here.
