<i>catena</i>-Poly[[[bis(quinoxaline-2-carboxylato-κ² <i>N</i> ¹,<i>O</i>)zinc(II)]-μ₂-1,2-bis(pyridin-4-yl)ethene-κ² <i>N</i>:<i>N</i>′] hemihydrate]

The title complex, {[Zn(C₉H₅N₂O₂)₂(C₁₂H₁₀N₂)]·0.5H₂O} _<i>n</i> , has six-coordinate Zn^II ions with two <i>trans</i>-bidentate quinoxaline-2-carboxyl-ato ligands and a bridging 1,2-bis-(pyridin-4-yl)ethyl-ene ligand, resulting in polymeric chains along the [101] direction. The offset packing of these one-dimensional chains gives rise to inter-chain H⋯O and H⋯ring inter-actions.
