Chemistry Question on coordination compounds

Which of the following will give maximum number of isomers?

A

[Co(NH3)4Cl2][Co (NH_3)_4Cl_2]

B

[Ni(en)(NH3)4]2+[Ni(en)(NH_3)_4]^{2+}

C

[Ni(C2O4)(en)2]2−[Ni(C_2O_4 )(en)_2]^{2-}

D

[Cr(SCN)2(NH3)4]+[Cr(SCN)_2(NH_3)_4]^+

Answer

[Cr(SCN)2(NH3)4]+[Cr(SCN)_2(NH_3)_4]^+

Explanation

Solution

[Cr(SCN)2(NH3)4]+ [Cr(SCN)_2 (NH_3)_4 ]^+ Oxidation number of Cr is 6 shows linkage, geometrical and optical isomerism.
