poor pi-donor versus strong pi-donor
« on: January 17, 2010, 05:42:43 PM »
 Hi!

 Which pi-donating ligand from two given would be stronger and why? For example iodide-anion versus fluoride-anion or some oxygene-containing ligand versus similar sulfur-containing ligand.

Thanks a lot

The answer is "good pi-donor should be sufficiently weak splitter(weak-field ligand)" and then you should check spectrochemical series.
