Two chiral silver coordination polymers based on chiral pyridyl pyrazine ligands: A directional linear polymer and a non-directional zigzag polymer with repeating Λ,Δ-configuration

Two new chiral pyridyl pyrazine ligands reacted with silver(I) ion to form two different polymers—one with an achiral trigonal bipyramidal silver(I) chain and the other a chiral tetrahedral chain with an interesting repeating Λ,Δ-silver(I) configuration.
