Which of the following is correct about Tetraamminedithiocyanato-s cobalt(III) tris(oxalato)cobaltate(III)?

Options

A. Formula of the complex is `[Co(SCN)_(2)(NH_(3))_(4)][Co(o x)_(3)]`
B. It is a chelating complex and show linkage isomerism
C. it shows optical isomerism
D. it shows geometrical isomerism

Answer

B, C, D

Explanation

Formula of the complex `[Co^(III)(SCN_(2))(NH_(3))_(4)]_(3)[Co^(III)(o x)_(3)]`
Linkage isomerism is due to presence of `SCN^(-)`
optical isomerism is exhibited due to presence of `[Co(o x)_(3)]^(3-)` complex ion, which has asymmetric structure.
Geometrical isomerism is exhibited due to cationic part:
