Mononuclear–dinuclear helicate interconversion of dibromo{N,N′-bis[(S)-1-2-(pyridyl)ethyl]pyridine-2,6-dicarboxamidate}copper(ii) via a deprotonation–protonation process†
Abstract
The mononuclear complex dibromo{N,N’-bis[(S)-1-2-(pyridyl)ethyl]pyridine-2,6-dicarboxamidate}copper(II) reversibly converts to the dinuclear chiral (M)-helicate upon deprotonation–protonation of the
