Coordination Number And Denticity
In the complex [Co(en)3]3+, the coordination number of Co and denticity of en (ethane-1,2-diamine) are respectively:
Select the correct option:
Solution
6 and bidentate
Each en ligand donates through two nitrogen atoms, so en is bidentate. Three en ligands contribute 3 × 2 = 6 donor atoms attached to Co, therefore coordination number is 6.
