Select type of isomerism in :
Options:
Answer:
Solution:
Question Explanation:
The question asks to identify the specific type of isomerism exhibited by the provided dinuclear (bridged) coordination complex containing two cobalt centers.
Concept:
Isomerism in Coordination Compounds, Coordination Position Isomerism, Bridged Complexes. Solution:
The given complex is a dinuclear species where two Co³⁺ centers are bridged by two chlorine (Cl⁻) ligands. Coordination position isomerism occurs in such bridged complexes when there is an interchange of ligands between the two metal centers. In this structure, one cobalt is bonded to two ethylenediamine (en) ligands, while the other is bonded to three ammine (NH₃) and one pyridine (py) ligand.
An isomer could exist where these terminal ligands are redistributed between the two cobalt atoms (e.g., and ).
Final Answer: Option (D)
