Allylcytisine as a convenient scaffold for the construction of the π,σ-coordination compound {Acyt(H+)}[Cu8{Acyt(H+)}Cl10] with the unusual anionic 1D-coordination polymer

Abstract

The aim of this work is to develop a novel π-coordination compound with unusual architecture using allylcytisine (Acyt) as a suitable scaffold. The synthesis and structural characterization of {Acyt(H+)}[Cu8{Acyt(H+)}Cl10] (1) and Acyt itself have been performed, accompanied by quantum chemical studies. A distinctive feature of structure 1 is the formation of H-bonded pairs of two {Acyt(H+)} cations, showing the non-equivalent participation of its allyl group regarding to Cu+ coordination, thus forcing the organization of the acentric structure 1 with the unusually organized anionic copper(I) halide 1D-coordination polymer.
