The irreducible representations for the four ligands on ML4 (Figure; 1) belonging to C3v point

group is 2A1+ E. The energy of the d-orbitals on M considering only sigma-bonding is dz2 >dx2-y2

& dxy > dxz & dyz (Should be in non-bonding). the SALCs of Where, ₁,₂ have a1 symmetry and

43 and 44 have e symmetry (Figure:2) are stabilized to the same extent that the d-orbitals are

destabilized. Complete the MO diagram for ML4 ( given below) the ligand field only (i.e. the d-

orbitals).
