What does (en) mean in a chemical formula/ligands

  1. Jun 27, 2009 #1
    1. The problem statement, all variables and given/known data
    What is the coordination number of [Pt(en)3](ClO4)4


    2. Relevant equations



    3. The attempt at a solution

    I know the method to solve this one, I just have no idea what (en) is and if it is bidentate or polydentate (I've already tried monodentate and it was incorrect). Even the name of (en) would be fantastic!
    Thanks :)

    Most likely ethylenediamine.

    Yep. en = ethylenediamine. bidentate. Perchlorate is one of the non-coordinating anions. It is just there to balance the charge on the platinum.
