Abstract: In the title compound, {[Zn(C₈H₁₀O₄)(C₁₄H₈N₄)]·2H₂O}_n or [Zn(1,4-chdc)(PyPhen)]·2H₂O, where 1,4-chdc is the 1,4-cyclohexanedicarboxylate dianion and PyPhen is pyrazino[2,3-f][1,10]phenanthroline, the Zn^II atom is six-coordinated by one chelating PyPhen and two bidentate 1,4-chdc ligands, resulting in a distorted cis-ZnN₂O₄ octahedral geometry. The Zn^II centres are bridged by the 1,4-chdc ligands, forming an infinite one-dimensional helical chain. In addition, neighbouring chains interact through - interactions, generating a two-dimensional network.
