Could someone explain what the (en) means in Cd(en)Br2] ? Found it on Sapling.

En is short for ethylenediamine, a bidentate molecule.

[SophiaJenny3I]

Hi! en is shorthand for ethylenediamine (H2NCH2CH2NH2). It's a bidentate ligand, so when it's in a complex it contributes two to the coordination number. Hope this helps!

[Kyle_Lee_2B]

(en) is NH2CH2CH2NH2 (ethylenediamine) and is bidentate.

[Annie Tong 2G]

En is short for ethylenediamine C2H4(NH2)2, a bidentate molecule. So whenever you see en, it count for a coordination number of 2.

[Jeremy Wei 2C]

Hi, (en) is short for the bidentate molecule ethylenediamine. Hope that helps!

[Ruth Rosales 3D]

Hi, I had this question too so I googled it.

There are a lot of available charts with the abbreviations for chemical compounds. It would be helpful to save one of these charts as a future reference.

As mentioned in other replies, (en) is for ethylenediamine (H2NCH2CH2NH2).

[Lauren Mungo 1K]

(en) is ethylenediamine and is a bidentate ligand

[Jessica Manriquez 1H]

(en) is short for ethylenediamine and it is a bidentate ligand

[Brandon McClelland3L]

It's shorthand for ethylenediamine.

[Aydin Karatas 1F]

(en) is short for ethylenediamine (H2NCH2CH2NH2). It is a bidentate ligand (from the two nitrogens) and contributes 2 to the coordination number of the central atom.

Hope this helps.

[sabrina ghalambor 2J]

hi! en is shorthand for NH2CH2CH2NH2, which is ethylenediamine, a bidentate ligand.

[alexandralopez 3F]

(en) is just the abreviation of ethylenediamine and it is a ligand

[Diana Aguilar 3H]

Thank you to everyone for the clarification, I also was wondering what that meant as well!

[rita_debbaneh2G]

En is the abbreviation for the coordination compound ethylenediamine. It's a bidentate ligand which means that its nitrogens donate their lone pairs when it acts as a donor.

[Colin Squire 3B]

Hello, "en" is just short for ethylenediamine! When doing the question don't forget that it is a bidentate! This messed me up a little too. Hope this helped!

[David Jen 1J]

(en) is short for ethylenediamine. I'm pretty sure there are more compounds that have similar naming nature so make sure to read about those ones too as it might be on the test!

[Jose Miguel Conste 3H]

it is short for ethylenediamine

[rhettfarmer-3H]

En is a ligand which is the short name for ethylenediamine. The key thing to remember here is that ethylenediamine or en is bidentate. Therefore, when counting for coordination number count this as 2 ligands. Confusing but check out the ligand page Lavalle has it helps a lot.

[joshtully]

It stands for ethylenediamine, which is a bidentate ligand.
