Question
In which of the following complexes more than one type of structural isomerism is possible ?
Options
A.[Co(NH3)5 (NO2)]Cl
B.[Co(NH3)5(H2O)](NO2)3
C.[Pt(NH3)4][Pt(SCN)4]
D.[Cr(NH3)4 (NO2)2] (NO3)2
Solution
(A) [CoII(NH3)5(NO2)]Cl and [CoII(NH3)5(ONO)]Cl - linkage isomerism
[CoII(NH3)5(NO2)]Cl and [CoII(NH3)5Cl]NO2 - ionization isomerism
(B) [CoII(NH3)5(H2O)](NO2)3 and [CoII(NH3)5(NO2)](NO2)2.H2O - hydrate isomerism
[CoII(NH3)5(NO2)](NO2)2.H2O and [CoII(NH3)5(ONO](NO2)2.H2O
(C) [PtII (NH3)4]2+ [PtII(SCN)4]2- and [PtII(NH3)3(SCN)]+ [PtII(NH3)(SCN)3]- - coordination isomerism
[PtII(NH3)4]2+ [PtII(SCN)4]2- and [PtII(NH3)4]2+ [PtII(NCS)4]2- - linkage isomerism
(D) [Cr(NH3)4(NO2)2](NO3)2 and [Cr(NH3)4(NO3)2](NO2)2 - ionization isomerism
[Cr(NH3)4 (NO2)2] (NO3)2 and [Cr(NH3)4 (ONO)2] (NO3)2 - linkage isomerism
[CoII(NH3)5(NO2)]Cl and [CoII(NH3)5Cl]NO2 - ionization isomerism
(B) [CoII(NH3)5(H2O)](NO2)3 and [CoII(NH3)5(NO2)](NO2)2.H2O - hydrate isomerism
[CoII(NH3)5(NO2)](NO2)2.H2O and [CoII(NH3)5(ONO](NO2)2.H2O
(C) [PtII (NH3)4]2+ [PtII(SCN)4]2- and [PtII(NH3)3(SCN)]+ [PtII(NH3)(SCN)3]- - coordination isomerism
[PtII(NH3)4]2+ [PtII(SCN)4]2- and [PtII(NH3)4]2+ [PtII(NCS)4]2- - linkage isomerism
(D) [Cr(NH3)4(NO2)2](NO3)2 and [Cr(NH3)4(NO3)2](NO2)2 - ionization isomerism
[Cr(NH3)4 (NO2)2] (NO3)2 and [Cr(NH3)4 (ONO)2] (NO3)2 - linkage isomerism
