aqa chemistry help!

aqa chemistry help!

hi guys, can someone help me as to how i should he understanding cis-trans isomerism - especially in square planar complexes.
i understand a complex is cis when the ligands that are the same are together - but is this the case both horizontally and vertically.
For example - for cis-platin, can the chloride ligands be together on one side vertically and still be cis or must it be horizontally?
thanks :smile:

in square planar the cis trans isomerism is same to E/Z, same side cl=cis, diagonal from each other cl=trans, yes this is same for horizontally and vertically
