catena-Poly[[[triaquacopper(II)]-μ-2,2′-bipyridine-3,3′-dicarboxylato-κ³N,N′:O] monohydrate]

Abstract

The title compound, {[Cu(C12H6N2O4)(H2O)3]·H2O}n, was synthesized under hydro­thermal conditions. The Cu2+ ion is six-coordinated by three water O atoms, and two N atoms and one O atom of the 2,2′-bipyridine-3,3′-dicarboxyl­ate bridging ligand in a sligthly distorted octa­hedral environment. The 2,2-bipyridine-3,3′-dicarboxyl­ate bridges link the Cu2+ ions into chains along the b-axis direction. These chains are further linked by O—H⋯O hydrogen bonds involving the water solvent mol­ecules, forming a three-dimensional framework.

“…Their structures vary from one-dimensional to three-dimensional architectures (Qiu & Zhu, 2009;Du & Bu, 2009). Our recent research interest has been focused on the synthesis of novel coordination polymers (Pan, Cheng & Bu, 2010Pan, Cheng & Hu, 2010;Pan, Li et al, 2010;Pan, Ma et al, 2012;Wu et al 2011). Here we present a Gacontaining coordination polymer with a one-dimensional chain structure.…”
