Calibrating the coordination chemistry tool chest: metrics of bi- andtridentate ligands

摘要

Bi- and multidentate ligands form part of the tools commonly used for designing coordination andsupramolecular complexes with desired stereochemistries. Parameters and concepts usually employedinclude the normalized bite of bidentate ligands, their cis- or trans-coordinating ability, their rigidity orflexibility, or the duality of some ligands that can act in chelating or dinucleating modes. In thiscontribution we present a structural database study of over one hundred bi- and tridentate ligands thatallows us to parametrize their coordinating properties and discuss the relevance of such parameters forthe choice of coordination polyhedron or coordination sites.
