Quizplus · Accepted Answer

Structures 3 and 4 are square planar with two different ligands and two bidentate ligands, respectively. Therefore, they are geometric isomers. Structures 1 and 2 are octahedral but have different ligands, so they are also geometric isomers. Therefore, the correct choice is E.
