# Problem: There are two geometric isomers of octahedral complexes of the type MA3X3 (Figure 1), where M is a metal and A and X are monodentate ligands.Of the complexes shown here, which are identical to (1) and which are the geometric isomers of (1)? Complex 2, Complex 3, Complex 4, Complex 5.

###### FREE Expert Solution

We are asked which are identical to (1) and which are the geometric isomers of (1).

Rotating the structures will show us that it is identical to (1):

Rotating (3) about the vertical axis by 180° will make it look like (1):

Rotating (3) about the vertical axis by 90° will make it look like (1):
