In the title VIV complex, [VO(C13H15NO3)(C12H8N2)], the oxidovanadium cation is N,N′-chelated by a 1-10-phenanthroline ligand and N,O,O′-chelated by a Schiff base anion in a distorted octahedral geometry. Weak intermolecular C—H⋯O hydrogen bonds occur in the which contains solvent-accessible voids of 81 Å3.

L-Leucine (1 mmol, 131.2 mg) and potassium hydroxide (1 mmol, 56.1 mg) were dissolved in hot methanol (10 ml) with stirring and added successively to a methanol solution (5 ml) of salicylaldehyde (1 mmol, 0.11 ml). The mixture was then stirred at 323 K for 2 h. Subsequently, an aqueous solution (2 ml) of vanadyl sulfate hydrate (1 mmol, 225.4 mg) was added dropwise and stirred for 2 h continuously. Finally, a methanol solution (5 ml) of 1,10-phenanthroline (1 mmol, 198 mg) was added dropwise and stirred for 2 h. Then the resultant solution was filtered and the filtrate was held at room temperature for several days, whereupon yellow blocky crystals suitable for X-ray diffraction were obtained.
All the H atoms were placed in geometrically calculated positions, with C—H = 0.93–0.98 Å and allowed to ride on their respective parent atoms, with Uiso(H) = 1.2Ueq or 1.5Ueq(Cmethyl).
Vanadium complexes have have been synthesized and characterized continuously due to its biological and pharmacological properties (Baran, 2003). Herein, we report the synthesis and
of a new oxovanadium(IV) complex with a tridentate Schiff base ligand derived from the condensation of salicylaldehyde and L-Leucine, with a 1,10-phenanthroline coligand.As shown in Fig. 1, the central V(IV) ion is six-coordinated bound to two O atoms and one N atom of the Schiff base ligand, a vanadyl O atom and two N atoms of the 1,10-phenanthroline ligand, forming a distorted octahedral geometry. Selected bond angles and bond distances of the title complex are given in Table 1.
In the molecular structure of the complex, O1, N1, O3 and N2 atoms are in the equatorial plane, O4 and N3 is in the axial position. The V1 ion lies 0.3485 (17) Å above the equatorial plane towards O4. The V1—N3 bond is significantly longer [2.340 (3) Å] (Table 1), similar to the reported vanadium(V) complex (Bian et al., 2011; Cao et al., 2011; Xu et al., 2005; Li et al., 2010; Li et al., 2006;).

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. |

Vanadium complexes have have been synthesized and characterized continuously due to its biological and pharmacological properties (Baran, 2003). Herein, we report the synthesis and crystal structure of a new oxovanadium(IV) complex with a tridentate Schiff base ligand derived from the condensation of salicylaldehyde and L-Leucine, with a 1,10-phenanthroline coligand.
As shown in Fig. 1, the central V(IV) ion is six-coordinated bound to two O atoms and one N atom of the Schiff base ligand, a vanadyl O atom and two N atoms of the 1,10-phenanthroline ligand, forming a distorted octahedral geometry. Selected bond angles and bond distances of the title complex are given in Table 1.
In the molecular structure of the complex, O1, N1, O3 and N2 atoms are in the equatorial plane, O4 and N3 is in the axial position. The V1 ion lies 0.3485 (17) Å above the equatorial plane towards O4. The V1—N3 bond is significantly longer [2.340 (3) Å] (Table 1), similar to the reported vanadium(V) complex (Bian et al., 2011; Cao et al., 2011; Xu et al., 2005; Li et al., 2010; Li et al., 2006;).
In the crystal structure, weak intermolecular C—H···O hydrogen bonds (Table 2) occur.
