'm trying to get better at drawing qualitative MO diagrams using ligand SALCs. However, I'm having difficulties understanding the ordering of ligand SALCs in complexes that aren't octahedral. For example, in an octahedral complex, the SALCs w/a1g symmetry has zero nodes, the SALC w/t1u symmetry has one node, and thee SALC w/eg symmetry has two nodes. For a square planar complex, the a1g SALC still has zero nodes and is lowest in energy, but the b1g SALC, for which I'm counting two nodes, is the ...
