Abstract

In the title compound, {[Zn(C₁₆H₁₂N₂O₅)]·H₂O}_n, the unique Zn^II ion is coordinated in a distorted square-pyramidal environment by three O atoms and one N atom from a symmetry-unique ligand. A symmetry-related ligand provides an O atom from a carboxylate group to complete the coordination in the apical site and generate a one-dimensional polymer parallel to [010]. In addition to an intramolecular O—H⋯N hydrogen bond, intermolecular O—H⋯O and weak C—H⋯O hydrogen bonds are observed within the one-dimensional structure.

Comment

Zn(II) carboxylates, especially those with nitrogen donor ligands, have been the subject of numerous investigations (Suen et al., 2002). Different coordination modes of carboxylate groups can form mononuclear and polynuclear structures. Hydrazone with carboxylate groups can also form mononuclear and polynuclear structures in different conditions (Wu et al., 2007; Luo et al., 2010). Herein we report the synthesis and crystal structure of the title compound.

Part of the one-dimensional structure is shown in Fig. 1. The unique Zn^II ion is coordinated in a distorted square-pyramidal environment by three O atoms and one N atom from a symmetry unique ligand. A symmetry related ligand provides an O atom from a carboxylate group to complete the coordination in the apical site and generate a one-dimensional polymer parallel to [010] (Fig 2). In addition to an intramolecular O—H···N hydrogen bond, intermolecular O—H···O and weak C—H···O hydrogen bonds are observed within the one

Experimental

The hydrazone ligand was synthesized according to the literature procedure (Luo et al., 2010). Zinc(II) acetate monohydrate (1 mmol) was dissolved in methanol (15 ml), to which a solution of the ligand (2.5 mmol) in dimethylformamide (15 ml) was added. The mixture was stirred for 3 h at room temperature. An light-yellow solution was obtained, the solution was filtered and allowed to stand at room temperature for three weeks, where upon colorless block-shaped crystals were obtained.
