What's the correct way to count chelate rings in [Co(EDTA)]-?

Click For Summary
SUMMARY

The correct way to count chelate rings in the complex [Co(EDTA)]- involves identifying the distinct cycles formed by the ligand EDTA. In the provided diagram, there are five purple linkages that indicate the presence of five chelate rings. This method of visual representation is essential for accurately determining the coordination number and geometry of the cobalt complex.

PREREQUISITES
  • Understanding of coordination chemistry
  • Familiarity with chelation and chelate ligands
  • Knowledge of the EDTA (ethylenediaminetetraacetic acid) structure
  • Ability to interpret molecular diagrams
NEXT STEPS
  • Research the properties of EDTA as a chelating agent
  • Learn about coordination numbers in transition metal complexes
  • Explore the geometry of cobalt complexes in coordination chemistry
  • Study methods for visualizing molecular structures and cycles
USEFUL FOR

Chemistry students, researchers in coordination chemistry, and professionals working with metal-ligand complexes will benefit from this discussion.

TL;DR
What are the five chelate rings in [Co(EDTA)]-
Since I can't find a definition I just drew cycles.
