A tris(2-quinolylmethyl)amine scaffold that promotes hydrogen bonding within the secondary coordination sphere

Abstract

A new quinolyl-based ligand presents three amide functionalities to act as hydrogen-bond accepting groups to a metal-bound substrate at a well-defined distance. As a confirmation of the design strategy, CH₃CN coordinated to copper(II) participates in CH–O interactions in the solid state and in solution.
