For a trigonal planar complex (i.e.g. $[AgCl_3]^{2-}$$\ce{[AgCl_3]^2-}$):
According to this image: (http://plato.mercyhurst.edu/chemistry/kjircitano/InorgStudysheets/InorgStudyExamIII_files/image016.gifsource):
The $x^2 - y^2 $and$x^2 - y^2$ and $xy$ orbitals are on the same energy level. However, assuming that one of the Cl$\ce{Cl}$ ligands lies on the $y$ axis (or the $x$ axis), wouldn't the $x^2 - y^2 $$x^2 - y^2$ orbital be higher in energy? Thanks in advance.
