if the complex looks like

[Co(NH3)4Br2]+ then there will be no optical isomerism could u be more specific in showing the coordinate sphere

actually question is like this only...question says to count no. of isomers..surely there will be ionisaton isomerism ...but i am not sure about optical...

becoz everytime i have seen en ligand in optical

not always for example only the cis isomer of the form [MX2(en)2] shows optical activity.

geometrical,optical,ionisation isomerism.

well,eure,i don't think this compound will show optical isomerism. its true that the octahedral complexes

having bidentate groups usually show optical isomerism and this compound too has coordination number - 6.

but,the ion Co[(NH3)4 Br2]+ ion wouldn't have any enantiomeric form.

rather it will show geometrical and ionisation isomerism.

tahts what i thought and forced me to put up question here

RSM says taht it will show ionisation and optical isomerism[7]

But what if complex is [Co(NH3)4BrCl]Br? Then optical isomerism is also possible . Please validate this point
