What is the charge on H2O Ligand?

The H2O ligand is neutrally charged, the same way that water itself is neutral. How then does it act as a ligand? read more

H2O comes under the category of intermediate field ligand because it donates only through sigma bonding. The reason it is not weak ligand is it cannot donates through pi bonding i.e only sigma donor, because after donating one electron pair oxygen attains positive charge which makes it difficult to donate another pair of electron. read more

A ligand exchange (also ligand substitution) is a type of chemical reaction in which a ligand in a compound is replaced by another. One type of pathway for substitution is the ligand dependent pathway. read more

Because Mn is a first row transition metal, relatively low oxidation state, with a weak field ligand, the complex will be high spin with 5 unpaired electrons. So if you have a weak ligand, the complex is high spin. read more
