What is the EAN of Mn(CO)(NO)3
Answers
Explanation:
According to Sidwick Central metal ion of coordination complex will continue accepting electron pairs till the total number of electrons in the metal ion and those donated by ligands is equal to that of the next higher noble gas. This total number of electrons is called effective atomic number (EAN) of the metal. However this rule is more valid for non classical complexes specially carbonyl compounds hence this rule used for determining Stoichiometry, stability. Oxidizing and reducing character of carbonyl compounds.
CALCULATION OF EAN:
Total number of electrons possessed by the central atom in a complex is called Effective Atomic Number (EAN).
EAN = Z-(OS) Oxidation State + 2*coordination Number
This is Not applicable for pi complex
EAN = Z-(OS) Oxidation State + Total Number of electrons gained from ligands
