Flexible “piperazine–pyrazine” building blocks: conformational isomerism of “equatorial–axial” sites toward the constructions of silver(i) coordination chains

Abstract

The Ag(bpzp)-based coordination polymers are susceptible to the influence of both the conformational isomerism of “equatorial–axial” donating sites of the conformationally flexible bpzp ligand and the capability of anion coordination, resulting in different one-dimensional snake-like chain structures that feature a linear, a slightly off linear, and a zig-zag pattern.
