Discussion Overview

The discussion revolves around the identification and characteristics of the ligand represented by (en) in the chemical formula [Pt(en)3](ClO4)4. Participants explore the nature of (en) and its role in coordination chemistry, specifically regarding its denticity.

Discussion Character

  • Homework-related, Conceptual clarification

Main Points Raised

  • One participant seeks clarification on what (en) represents in the context of the coordination complex and its denticity.
  • Another participant proposes that (en) most likely refers to ethylenediamine.
  • A later reply confirms that (en) is indeed ethylenediamine and states that it is bidentate.
  • It is noted that perchlorate acts as a non-coordinating anion, serving to balance the charge on the platinum.

Areas of Agreement / Disagreement

There appears to be agreement among participants regarding the identification of (en) as ethylenediamine and its classification as bidentate. However, the initial uncertainty about the ligand's nature indicates that the discussion is still somewhat exploratory.

Contextual Notes

Participants do not delve into the specifics of coordination numbers or the implications of the ligand's denticity on the overall complex structure.

Who May Find This Useful

Students or individuals interested in coordination chemistry, particularly those studying ligands and their properties in chemical formulas.

Homework Statement


What is the coordination number of [Pt(en)3](ClO4)4

Homework Equations


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.
 
Thanks so much :)
 
Yep. en = ethylenediamine. bidentate. Perchlorate is one of the non-coordinating anions. It is just there to balance the charge on the platinum.
 
Thank you :)
