In the crystal structure of the title compound, [V₂(C₂₂H₂₁N₂O₂)₂O₄]·2H₂O, oxide-bridged dimers of the complex are linked to water molecules by hydrogen-bonding interactions. The two five-membered chelate rings in the dimeric molecule both adopt twist conformations. Each V^V atom is six-coordinated by one oxide group and by two N and one O atom of the tridentate Schiff base ligand, and is bridged by two additional oxide atoms. The metal centre has a distorted octahedral coordination. The monoanionic ligands occupy one equatorial and two axial positions.

Comment top

The discovery of vanadium in active sites of biological systems of nitrogenase (Robinson et al., 1986) and bromoperoxidase (Vilter, 1984) and recognition of its environment increased the interest in the vanadium complexes with ligands bearing oxygen and nitrogen atoms for mimicking the biological activity in natural systems. Structural models for the active site in haloperoxidases have already been reported (Gruning & Rehder, 2000; Casny & Rehder, 2001; Kimblin et al., 2002). Recently, it has been established that vanadium(V) complexes with Schiff bases, which are excellent models for active sites of vanadium containing haloperoxidases, are able to catalyze the oxidation of organic sulfides to the corresponding sulfoxides (Kwiatkowski et al., 2003, 2007; Romanowski et al., 2008). Vanadium haloperoxidases catalyze the oxidation of halides in the presence of hydrogen peroxide to highly reactive intermediate, a hypohalous acid, which may react either with suitable nucleophilic acceptor, if present, forming a halogenated compound or with hydrogen peroxide yielding ¹O₂ (Wever & Hemrika, 1997). Lately, it has been shown that vanadium bromoperoxidase from marine red algae can catalyze the bromination and cyclization of terpene substrates or the selective sulfoxidation of sulfides to the sulfoxides (Butler & Carter-Franklin, 2004).

The structure of (I) indicates that each vanadium atom is six-coordinated. The vanadium atoms V27 and V27A are joined together through two oxygen bridges, O29 and O29A being the bridging atoms coordinated to vanadium atoms at short and long distances (Table 1 and Fig. 1). The coordination sphere around each vanadium atom is composed of phenolate oxygen atoms (O7 or O7A) and of primary amine nitrogen atom (N14 or N14A) occupying axial positions and of imine nitrogen atom (N11 or N11A), two strongly coordinated terminal oxo (O28, O29 or O28A, O29A) and one weakly associated oxo group (O29A or O29) derived from the neighbouring VO₂ unit defining the equatorial plane. The polyhedron that describes the quadrilateral core consisting of the V₂O₂ unit and the spatial arrangement of remaining coordinated atoms resembles two edge shared octahedrons that are significantly distorted. The V27=O28 and V27A=O28A bond lengths of 1.616 (4) and 1.612 (4) Å respectively compare well with the distances between vanadium and the doubly bonded oxygen atoms (Root et al., 1993; Romanowski et al., 2008). The V27—O29 and V27A—O29A bonds (average 1.696 (4) Å) are longer than V27—O28 and V27A—O28A bonds (average 1.614 (4) Å) due to involvement of O29 and O29A atoms in V27—V27A bridging and hydrogen bonding interactions with water molecules. The V27—V27A distance of 3.057 (2) Å is much shorter than the V(V)—V(V) distance of 3.204 Å found in similar complex (Romanowski et al., 2008). The O28—V27—O29 and O28A—V27A—O29A angles of 105.6 (2)° and 104.6 (2)° respectively indicate significant double bond character of these bonds (Colpas et al., 1994) and are close to other cis-VO₂ units (Li et al., 1988). The two five-membered chelate rings adopt twisted conformations, while in similar dimeric vanadium(V) complex adopt differently puckered envelope conformations (Romanowski et al., 2008). The rings defined by V27, N11, C12, C13, N14 and V27A, N11A, C12A, C13A, N14A choose twisted conformation on C12, C13 and C12A, C13A, respectively.

The crystal structure of (I) is stabilized by intermolecular hydrogen bonds linking dimeric molecules both directly by N—H···O interactions and indirectly through water molecules by O···H—O—H interactions (Fig. 2, Table 2).

Experimental top

The complex (I) were obtained in a template/complexation reactions analogous to those described for preparation of dioxovanadium(V) complexes with Schiff base ligands (Kwiatkowski et al., 2003). A solution of 1 mmol of (R,R)-(+)-1,2-diphenyl-1,2-diaminoethane in 10 ml of absolute ethanol was added under stirring to a freshly filtered solution of vanadium(V) oxytriethoxide (1 mmol) in 50 ml of absolute EtOH producing a yellow suspension of the intermediate. 3-Methoxysalicylaldehyde (1 mmol) dissolved in absolute EtOH was added to the aforementioned suspension. After refluxing (70 ml) of the resulting mixture for 2 h and its cooling to room temperature the separated solids were filtered off, washed several times with EtOH, recrystallized from DMSO-EtOH mixture and dried over molecular sieves.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
