Di-[mu]-oxido-bis({2-[(R,R)-(-)-(2-aminocyclohexyl)iminomethyl]-4-nitrophenolato-[kappa]3N,N',O}oxidovanadium(V)) dimethyl sulfoxide disolvate

Abstract top

The title compound, [V2(C13H16N3O3)2O4]·2C2H6OS, is a centrosymmetric dimeric complex solvated by two dimethyl sulfoxide molecules. Each VV atom is six-coordinated by one oxide group, two N atoms and one O atom from the tridentate Schiff base ligand, and by two additional bridging O atoms in a distorted octahedral coordination geometry. Three atoms of the cyclohexane ring are each disordered over two sites, with occupancy factors of 0.501 (10) and 0.499 (10). C-H...O and N-H...O hydrogen bonds link the dimers and solvent molecules into a supramolecular network.

Comment top

Research in vanadium chemistry and biochemistry increased after discovery of insulin mimetic (Rehder et al., 2002), anticancer (Evangelou, 2002), antifungal and antibacterial (Parekh et al., 2006; Shahzadi et al., 2007) activity of this element. Oxidovanadium(IV) and (V) compounds exert catalytic activity like some biological enzymes, viz. haloperoxidases (Carter-Franklin et al., 2003; Rehder et al., 2003), phosphomutases (Mendz, 1991) and nitrogenases (Eady, 2003). Moreover, investigation of vanadium(V) complexes with Schiff bases is prompted by the fact that these ligands are coordinated to the metal through O and N atoms, similar to the coordination environments of natural systems.

The title compound was earlier characterized by spectroscopic methods (IR, UV-Vis, 1H and 51V NMR) (Kwiatkowski et al., 2007). The crystal structure consists of a centrosymmetric dimeric vanadium(V) complex and two dimethyl sulfoxide (DMSO) molecules (Fig. 1). The singly deprotonated Schiff base acts as a tridentate ligand, forming one five- and one six-membered chelate rings. Each VV atom is six-coordinated in a distorted octahedral environment. Two axial positions are occupied by one phenolate O atom (O22) and one amine N atom (N18), and the equatorial positions are occupied by one azomethine N atom (N11), two strongly [O20i and O21i; symmetry code: (i) -x, -y + 1, -z + 2] and one weakly (O21) bonded oxide groups (Fig. 1). The V19—O20, V19—O21i(bridging) and V19—O22(phenolate) bond distances (Table 1) agree well with the corresponding values reported for related compounds (Mokry & Carrano, 1993; Romanowski et al., 2008; Root et al., 1993). The V19—O21 bond is longer than O21—V19i bond due to the involvement of this O atom in bridging between the V atoms. The V19, O21, V19i, O21i atoms are situated in the vertices of a parallelogram with the acute O21—V19—O21i angle of 77.9 (2)°. The V···V separation is 3.170 (1)Å and falls within the range of known V···V distances in double-bridged vanadium polynuclear systems (Mokry & Carrano, 1993; Romanowski et al., 2008; Root et al., 1993). Three C atoms of the cyclohexane ring exhibit twofold disorder. The C12, C15 and C17 atoms are each disordered over two sites, with occupancy factors of 0.501 (10) and 0.499 (10). The five-membered chelate ring defined by V19, N11, C12, C17, N18 adopts a twisted conformation on C12 and C17 atoms, with P = 250.3 (5)° and τ(M) = 56.7 (6)° for reference bond V19—N11 (Rao et al., 1981) (Fig. 1).

In the crystal structure, C—H···O and N—H···O hydrogen bonds link the dimers and solvent molecules into a supramolecular network (Table 2; Fig. 2).

Experimental top

The title compound was obtained in a template/complexation reaction analogous to that described for preparation of dioxidovanadium(V) complexes with Schiff base ligands (Kwiatkowski et al., 2003). A solution of R,R-(–)-1,2-diaminocyclohexane (1 mmol) in absolute ethanol (10 ml) was added under stirring to a freshly filtered solution of vanadium(V) oxytriethoxide (1 mmol) in absolute ethanol (50 ml), producing a yellow suspension of the intermediate. 5-Nitrosalicylaldehyde (1 mmol) dissolved in absolute ethanol was added to the aforementioned suspension. After refluxing of the resulting mixture (70 ml) for 2 h and its cooling to room temperature, the separated solids were filtered off, washed several times with ethanol, recrystallized from DMSO–EtOH mixture and dried over molecular sieves.

Refinement top

All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93–0.98 and N—H = 0.90 Å, and with Uiso(H) = 1.2(1.5 for methyl group)Ueq(C,N).
