Remember, there's cis isomer, trans isomer, etc.

anonymous · Answer

Ya, and cis is optically active. So for cis no. Of isomers should  be 2X2X2 = 8  ( as SCN and NO2 show linkage isomerism).
And for trans it should be 4 ( no optical isomerism). So total should be 12. 

I wonder why the answer is given as 24.....

Well, you can rearrange the dentate, I assume. But overall, you would still have the same structure.

anonymous · Answer

en plus il existe des isomeries optiques .. car il n y a pas un element de symetrie ................... isomeris de liaison aussi entre (SCN et NCS ) et (NO2 et ONO ) ........... isomerie  structurale (changement ) entre NO2 et Cl par example  [Co(en)2 SCN Cl ]NO2 ................  isomeries giometriques Cis Trans ........ so totaly is over of 10 isoms -----(the text is in french)-----
