Catena-Poly[[[(2,2′-bipyridyl-κ2N,N′)zinc(II)]-μ3-(5-hydroxyisophthalato-κ4O,O′:O′′:O′′′)] monohydrate

Abstract

The title compound, {[Zn(C8H4O5)(C10H8N2)]·H2O}n, was synthesized by reacting Zn(NO3)2, 5-hydroxy­isophthalic acid and 2,2′-bipyridine under hydro­thermal conditions. Self-assembly between the bridging ligands, chelating ligands and metal ions results in a one-dimensional coordination polymer, in which the ZnII atom is six-coordinate and shows a [ZnN2O4] octa­hedral geometry. The ribbons are inter­connected by an extensive network of hydrogen bonds involving the water mol­ecule, the hydroxyl group and the carboxyl­ate O atoms, forming a two-dimensional layer. These layers are connected through π–π inter­actions between the pyridyl rings [centroid-to-centroid distance 3.57 (1) A].
