Substitution in Square Planar Metal Complexes
... Metal effects on square planar substitution: • almost all examples of square planar geometry are d8 electron counts so electron counts are not a factor • however, ∆CFSE going from SqP to TBP geometry is still unfavourable by -0.242∆oct so this adds to the barrier for square planar substitution and ...
