Abstract

Graphical abstract: Abstract: A competitive formation of ' anti ' symmetric di-Cu II and ' syn ' non-symmetric decarboxylated di-Cu II complexes was established from a systematic study of Cu II binding to aminocarboxylate-based bis-glycinamide ligands featuring a His/His dyad, due to the Δ–Λ interconversion of backbone conformation which gave rise to anti versus syn binding for the 2nd Cu II . The findings provide a facile strategy for the investigation of novel di-Cu II mimics.
