For this problem, I am having a little bit of trouble understanding why [Pt(en)Cl2] does not have a coordination number of 2? What is it and how did you get this answer?

[Maleeha Zaman 1K]

Hi, en represents ethylene diamine which is bidentate ligand. Thus the coordination number will be 4, 2 bonds to the central atom from en and 2 bonds from the chlorines.

Hi, so the en ligand is bidentate, so the central atom has a coordination number of 4 and not 3.

[Kiku Shirakata 2A]

Hello,

In the metal complex [Pt(en)Cl2], the en (ethylenediamine, H2NCH2CH2NH2) ligand is bidentate, which means it has two donor atoms. So each en ligand in a complex contributes two to the coordination number.

Hope this helps!
