Poly[2-aminopyridinium [aquacuprate(II)-₄-5-sulfonatosalicylato]]

S.-R. Fan and L.-G. Zhu

Abstract: The title complex, {[Cu(C₇H₃O₆S)(H₂O)](C₅H₇N₂)}_n, consists of a polymeric anionic chain and protonated 2-aminopyridine. In the chain, each Cu^II atom has a distorted octahedral environment. The fully deprotonated 5-sulfonatosalicylate ligand acts as a ₄-bridging link, resulting in a dinuclear Cu₂O₆ motif. N-HO hydrogen bonds between cations and anions lead to a two-dimensional architecture.
