 Hi Everybody,
 Is it reasonable for a pi-complex to be higher in energy than the reactants from
 which it is formed? What will be the likely reason for such an occurrence?
 Or am  I doing something wrong in my calculations( DFT B3LYP/6-31G*)?
 I'll be glad if someone can offer me some insight.
 Thanks in advance for your help.
 Best regards.
