SUMMARY

The discussion centers on the isomers of the neutral octahedral complex [Fe(SCN)2(H2O)4]. Three distinct isomers are identified: trans-, cis-, and the mirror image of the cis-isomer. The participants clarify that the mirror image is indeed a different isomer due to its chiral nature. Additionally, the coordination of the thiocyanate ion (SCN-) is addressed, emphasizing its role in the overall structure of the complex.

PREREQUISITES
  • Understanding of octahedral coordination complexes
  • Knowledge of isomerism in coordination chemistry
  • Familiarity with chirality and mirror images in molecular structures
  • Basic concepts of ligand coordination, specifically regarding thiocyanate ions
NEXT STEPS
  • Research the concept of coordination chemistry and octahedral complexes
  • Study the different types of isomerism, focusing on geometric and optical isomers
  • Explore the properties and behavior of thiocyanate ions as ligands
  • Learn about chirality and its implications in coordination compounds
USEFUL FOR

Chemistry students, particularly those studying coordination chemistry, and educators seeking to enhance their understanding of isomerism in metal complexes.

Homework Statement


How many possible isomers exist for the neutral octahedral complex[Fe(SCN)2(H2O)4]?

Homework Equations





The Attempt at a Solution


i got three which are trans-, cis-, and the mirror image of cis-. so is there anymore?
please help.
 
Physics news on Phys.org
I don't see how the mirror image is different from the original.
 
How does the thiocyanate ion co-ordinate?
