NEETChemistryCoordination Compounds
What is the term used to describe isomerism in coordination entities like [Co(NH 3 ) 3 (NO 2 ) 3 ], where three donor atoms of the same ligands occupy adjacent positions at the corners of an octahedral face?
Options
- ACis isomer
- BTrans isomer
- CFacial (fac) isomer
- DMeridional (mer) isomer
Correct answer
C. Facial (fac) isomer
Step-by-step solution
When three donor atoms of the same ligands occupy adjacent positions at the corners of an octahedral face, it is referred to as the facial (fac) isomer.
