Strategy:
 Visualize the arrangement of ligands in the facial (fac) isomer of an  octahedral complex to determine the bond angles.

Step 1: Define the fac-isomer
In the fac- isomer, the three identical ligands (e.g., the three  ions) occupy the corners of one triangular face of the octahedron.

Step 2: Determine the angles
Because they are all on the same triangular face, each  is adjacent to the other two  ions.
The angle between any two adjacent positions in an octahedron is .
Since no  is opp
