Type of isomerism exhibited by [Cr(NCS)(NH3)5] [ZnCl4] :a)Coordination...
Coordination compounds often exhibit different types of isomerism due to the presence of different ligands and their arrangement around the central metal ion. One such compound is [Cr(NCS)(NH3)5] [ZnCl4], which exhibits both coordination and linkage isomerism.
Coordination Isomerism:
Coordination isomers are two compounds that differ in the way their ligands are coordinated to the central metal ion. In [Cr(NCS)(NH3)5] [ZnCl4], the two coordination isomers are:
- [Cr(NH3)5(ZnCl4)][NCS]
- [Cr(NH3)5(NCS)][ZnCl4]
In the first isomer, the ZnCl4- ion is coordinated to the chromium ion, while in the second isomer, the NCS- ion is coordinated to the chromium ion. Both of these isomers have the same formula weight and the same overall charge, but they differ in the way the ligands are coordinated.
Linkage Isomerism:
Linkage isomers are two compounds that differ in the way a particular ligand is coordinated to the central metal ion. In [Cr(NCS)(NH3)5] [ZnCl4], the two linkage isomers are:
- [Cr(NH3)5(NCS)][ZnCl4]
- [Cr(NH3)5(SCN)][ZnCl4]
In the first isomer, the NCS- ion is coordinated to the chromium ion through its nitrogen atom, while in the second isomer, the SCN- ion is coordinated to the chromium ion through its sulfur atom. Both of these isomers have the same formula weight and the same overall charge, but they differ in the way the NCS-/SCN- ion is coordinated.
Conclusion:
Thus, [Cr(NCS)(NH3)5] [ZnCl4] exhibits both coordination and linkage isomerism. Coordination isomers differ in the way the ligands are coordinated to the central metal ion, while linkage isomers differ in the way a particular ligand is coordinated to the central metal ion.
