Solution
The compound MX6 is octahedral. The number of X−M−X angles in the compound is 12. This is shown below. 4X atoms and M are in one plane. They form 4X−M−X angles. One X is above the plane. It forms 4X−M−X angles with 4X in the plane. One X is below the plane. It forms 4X−M−X angles with 4X in the plane.
