It is ethylenediammine. Which is basically two nitrogen atoms bonded together that can donate a pair of electrons to a metal

en stands for ethylenediamine! Note: this is a neutral ligand, meaning it provides no charge to the total complex. There is a list of various kinds of ligands in the 9C section of our textbook!

See "Naming Coordination Compounds" on Dr. Lavelle's website which gives all the neutral and anionic ligands. en is ethylenediamine, NH2CH2CH2NH2. Its two nitrogens have lone pairs which makes en a bidentate ligand.

I would try looking at the ligand sheets or quizlets to help with naming ligands! Found it super helpful!

Here is the link to the ligand naming sheet that Lavelle has on the website for easy reference.
