The title compound, [Zn₂Cl₂(C₂₀H₂₁N₃O)₂](ClO₄)₂·2H₂O, consists of a dinuclear Zn^II cationic complex, two disordered perchlorate anions and two water molecules as solvate. The [Zn₂(μ-Cl)₂(HL)₂]²⁺cation [HL is 2-({[2-(2-pyridyl)ethyl](2-pyridylmethyl)amino}methyl)phenol] has a centrosymmetric structure with the Zn^II ions in a distorted octahedral environment surrounded by an N₃OCl₂ donor set. HL acts as a tetradentate ligand through three N atoms from one amine group and two pyridyl arms and one O atom from the phenolic arm. The three N-donor sites of the HL ligand are arranged in meridional fashion, with the pyridine rings coordinated in trans positions with respect to each other. Consequently, the amine and phenol groups are trans to the asymmetric di-μ-chlorido exogenous bridges. A polymeric chain is formed along [010] by C(12)R₄²(8) intermolecular hydrogen bonding. The perchlorate anion is disordered and was modelled by two sites in a 0.345 (18):0.655 (18) ratio. Water–perchlorate O—H⋯O interactions form cyclic structures, while phenol–water O—H⋯O interactions generate an infinite chain. In addition, weak intermolecular C—H⋯π(Ph) interactions between pyridine donor and phenol acceptor groups of neighboring cations build a two-dimensional polymeric structure parallel to (110).

Comment top

Zinc is found in an all known forms of life as a trace element. It plays important roles in biological systems and its divalent ion is present in the active sites of several classes of metalloenzymes (Parkin, 2004). The design of artificial nucleases has recently received considerable interest due to their potential applications in catalysis, molecular biology and drug development (Mitić et al., 2006; Morrow & Iranzo, 2004; Rajski & Williams, 1998). Intense efforts have been devoted to the improvement of mimetic models for nucleases and peptidases through mono and polynuclear complexes (Boseggia et al., 2004; Mancin & Tecillia, 2007; Mitić et al., 2006). Recent studies have demonstrated that zinc complexes show anti-inflammatory and anti-tumoral activity (Beraldo & Gambino, 2004; Singla & Wadhwa, 1995; Zhou et al., 2003).

The cation of (I) is a dinuclear Zn^II complex showing centrosymmentric molecular structure with local symmetry C_i. Zinc(II) ions are in distorted octahedral environment surrounded by N₃O donor set of the HL ligand (HL is (2-pyridylethyl)(2-pyridylmethyl)(2-hydroxybenzyl)amine) and two Cl^- as exogenous bridges (Fig. 1). HL ligand acts as a typical four-chelating ligand and it is coordinated to the metal center through its three nitrogen atoms of the amine group and two pyridinic arms and one oxygen atom from protonated phenolic arm. The three N-donor sites of the HL ligand are arranged in meridional fashion, where pyridine rings are coordinated in trans positions with respect to each other. Consequently, the amine and phenol groups are trans to the asymmetric bis(µ-chloro) bridges.

Bond lengths around metal center are in the expected range and comparable to other zinc(II) complexes with N₂O donor set (Ojida et al., 2006; Trösch & Vahrenkamp, 1998; Gross & Vahrenkamp, 2005). The long distance Zn—O_phenol is typical for the coordination of protonated phenol group. The asymmetric bridge is due to the fact that two different groups with different trans effect are in trans positions to the chloro bridge. The distance Zn—Cl is shorter when amine group is trans to the bridge, whereas this distance is longer when phenol group is trans to µ-Cl. The cis angles are ranging from 77.69 (14)° to 100.55 (9)°, being the more closed angle restricted by a five-membered chelate ring formed by 2-methylpyridine arm. Although 2-ethylpyridine arm makes six-membered chelate ring, 2-methylpyridine arm also induces the greatest deviation from the ideal trans angle for N22—Zn1—N32.

The three-dimensional packing of (I) is governed by an extensive and interesting hydrogen bonding network (Fig. 2). Water molecules of crystallization and perchlorate anions form a cyclic structures by O1W—H···O interactions with a graph set of R₄²(8). These rings link the dinuclear cations through O10—H···O1W interactions between phenol and water groups building infinite one-dimensional chains along [010] direction with C(12) graph set. In addition, weak C—H···π(phenol) intermolecular interactions between pyridine (donor) and phenol (acceptor) groups of neighboring molecules also contribute to the stabilization of the crystalline structure aggregating the linear chains in two-dimensional polymer parallel to (110) plane. The calculated distance H35···centroid_phenol is 3.136 Å and the angle C35—H35—Centroid is 147.55°. Finally, the molecules of (I) are stacked viewing along [100] in perpendicular projection of the linear chains.

Experimental top

HL ligand has been prepared according to the procedure described by Yan & Que (1988). To a solution of HL (0.239 g, 0.78 mmol) in methanol (10 ml) was dropped 10 ml of the suspension containing 0.291 g of Zn(ClO)₄.6H₂O (0.78 mmol) in methanol. The mixture was stirred for 15 minutes at room temperature. After one hour on standing, a white precipitate was formed and it was filtered off and dried under vacuum (yield 0.63 g, 74%). The white powder was recrystallized in ethanol affording colorless crystals.
