Abstract

In the title complex, {[Zn(C4O4)(C12H8N2)(H2O)]·H2O}n, the penta­coordinated ZnII ion is bound to two N atoms of the 1,10-phenanthroline ligand, two O atoms from two bridging acetyl­enedicarboxyl­ate anions and a water O atom in a distorted trigonal–bipyramidal geometry. The crystal structure is characterized by polymeric zigzag chains running parallel to [2-10] and is stabilized by O—H⋯O hydrogen bonds.
