analysis on metal−π interactions has been performed,
and a geometrical correction, named as offset correction, has been
incorporated into the analysis to nullify the geometrical bias to
understand the geometrical preference for this interaction. The population
distributions of these interactions before and after offset correction
with respect to the offset from the centroid of the benzenoid ring
are completely different. In the cases of alkali metal−π
interactions, the population is maximum at offset zero or near zero.
However, in the case of transition metal−π interactions,
the offset for the maximum population is found near the carbon atom
of the benzenoid ring. Interestingly, alkaline earth metals, which
lie in between the alkali and transition metals in the periodic table,
behave in between these two metals when metal−π interaction
geometry is concerned.
