Abstract: In the title compound, [Zn(C₁₇H₁₂NO₄)₂(H₂O)₂], the Zn^II atom is located on a twofold rotation axis and is six-coordinated by four carboxylate O atoms from two chelating 9-allyl-6-carboxy-9H-carbazole-3-carboxylate ligands and two O atoms from two water molecules. In the crystal, O-HO hydrogen bonds link the molecules into a layer structure parallel to (-101).
