Bond length and bond multiplicity:
-bond prevents short
-bondsEluvathingal D. Jemmis, Biswarup Pathak, R. Bruce King and Henry F. Schaefer III
Analysis of model compounds such as Fe2(CO)6, C2 and HBBH shows that
-bonds left to themselves are shorter than
-bonds; in many ways
-bonds prevent
-bonds from adopting their optimal shorter distances.
