Type of isomerism exhibited by [Ir(OCN)2(H2O)3]a)Hydrate isomerismb)Li...
Explanation:
The given complex is [Ir(OCN)2(H2O)3]. It has two isomers, i.e., linkage and polymerization isomers.
Linkage Isomerism:
In linkage isomerism, the ligand can coordinate through a different atom of the same ligand to form a different compound. Here, the OCN^- ion can coordinate via nitrogen (N) or carbon (C).
- If OCN^- binds through N atom, it forms a linkage isomer.
- If OCN^- binds through C atom, it forms a normal isomer.
Hence, [Ir(OCN-N)2(H2O)3] and [Ir(OCN-C)2(H2O)3] are linkage isomers.
Polymerization Isomerism:
In polymerization isomerism, the ligand can have different bridging modes between two metal centers. Here, the OCN^- ion can act as a bridging ligand to form a polymer chain.
- If OCN^- bridges between two Ir centers, it forms a polymerization isomer.
- If OCN^- binds to only one Ir center, it forms a normal isomer.
Hence, [Ir(OCN)2(H2O)3] and [Ir(OCN)2(μ-OCN)(H2O)2] are polymerization isomers.
Conclusion:
Thus, the given complex exhibits both linkage and polymerization isomerism.
