Rezumat

The complex [Zn(OfPa)₂(H₂O)₄]·2H₂O (Ofpa is 2-formylphenoxyacetate) is synthesized and characterized by X-ray structural analysis and IR spectroscopy. The crystal is monoclinic: a = 25.254(5), b = 6.952(1), c = 13.951(3) Å, β = 116.41(3)°, Z = 4, space group C2/c, R = 0.034. The zinc atom in the centrosymmetric complex is coordinated by two monodentate carboxylate ligands (Zn-O 2.123(1) Å) and by four water molecules (Zn-O 2.085(1) and 2.092(2) Å). The oxygen atom of the aldehyde group is not involved in coordination. Complexes and solvate water molecules in the crystal are united into a three-dimensional framework via hydrogen bonds and π-π interactions.
