(10 pts.)Consider the [Ir2(dimen)4]²+ complex discussed in Lecture 1- 8. Notice that the dimen ligand is asymmetric. There is also a different, symmetric diisocyano ligand referred to as "TM4" (structure shown to the right) that forms the same sort of binuclear complex that dimen does. Answer the following questions with supporting justification: a. How many geometric isomers (ignore any optical ones) of [Ir2(TM4)4]²* are there? b. How many geometric isomers (ignore any optical ones) of [Ir2(dimen)4]²* are there? c. In the "twisted" deformational isomer, would you expect [Ir2(TM4)4]²+ or [Ir2(dimen)4]2+ to be able to rotate polarized light? Justify your answer.
