In a coordination compound, what does (en) stand for and how does it affect the coordination number of a metal species?

[amreen_sandhu1k]

it stands for ethylenediamine, H2NCH2CH2NH2) which is a bidentate ligand

[Lily Dabrowski 2G]

En is the abbreviation for ethylenediamine, which has the formula C₂H₄(NH₂)₂. The two nitrogen atoms each have one lone pair of electrons, meaning the whole molecule has two binding sites to bind to another metal atom or ion. This makes en a bidentate ligand. So, if a coordination compound contains one en molecule, that en would contribute two bonds to the central atom, which means it would add two to the coordination number of the whole compound.

[Crystal Ma 2J]

en stands for Ethylenediamine and it is bidentate, meaning it bonds to two places.

[105719095]

en stands for ethylenediamine and it is bidentate, meaning that it has two binding sites and adds 2 to the coordination number of the whole compound.
