摘要
Analysis of the crystal structures of a variety of transition metal complexes in which the ligands are hypodentate, thus providing pendent ammonio, amino, and/or hydroxy groups, has been conducted with the objective of defining the labile interactions of these pendent groups. In the case of pendent ammonio groups, not only do they appear to be good H-bond donors but they are frequently involved in contacts suggestive of hyperdenticity at N. For pendent amino and hydroxy groups, of particular interest in regard to their potential activity as nucleophiles, their H-bond acceptor ability frequently seems to be rather limited and it is unclear whether it can be related to either the nature or the charge on the bound metal cation.
