Six-Coordinate Compounds [M(Bidentate)3]
Repulsion energy calculations show that the stereochemistry corresponding to the single minimum on any potential energy surface always contains a threefold axis. The stereochemistry is, therefore, completely defined by the normalized bite of the bidentate ligand b and the angle of twist θ between the upper and lower triangular faces (Fig. 8.1). The regular octahedron corresponds to θ = 30°, and b = 21/2. The trigonal prism is the eclipsed arrangement with θ = 0°.
