trans-Bis(1,3-diphenylpropane-1,3-dionato)(methanol)oxidovanadium(IV) methanol disolvate

Abstract top

In the title compound, [V(C15H11O2)2O(CH3OH)]·2CH3OH, the VIV atom is coordinated by two 1,3-diphenylpropane-1,3-dionate ligands and an oxide ligand in an axial position. The sixth position is occupied by the O atom of a methanol group bonded trans to the oxide atom. The octahedral geometry is significantly distorted, with the VIV atom lying 0.330 (3) Å above the equatorial plane formed by the O atoms of the two [beta]-diketonate ligands. In the crystal, O-H...O hydrogen bonds between the coordinating methanol group in the complex and the two methanol solvent molecules lead to the formation of polymeric chains along the c-axis direction. Weak C-H...O contacts are also observed.

Comment top

The complex has two coordinated 1,3-diphenylpropane-1,3-dionato (dbm) ligands in the equatorial plane, the same as in the [VO(dbm)2] structure described by Schilde (Schilde et al., 1995). The oxido group is in the axial position and no significant change in bond length is reported for the O1—V1 bond of 1.5964 (3) Å as compared to the [VO(dbm)2] structure (1.5922 (4) Å). The sixth coordination position at the vanadium centre trans to the oxido is occupied by a methanol molecule. The rather long bond length of 2.302 (2) Å is similar to methanol coordination in structures by Gao (2.346 Å) (Gao et al., 1998), Chen (2.333 Å) (Chen et al., 2004) and Tasiopoulos (2.301 Å) (Tasiopoulos et al., 1999). A methoxy group bonded to a vanadium metal centre would have a V-OMe bond length of approximately 1.755 Å (Bansse et al., 1992).

Intermolecular O6—H6A···O7 hydrogen bonding in the order of 2.644 (2) Å was observed with a methanol solvent molecule. Additional intermolecular hydrogen bonding was also noted between O7—H7A···O8i of the order 2.749 (2) Å and O8—H8A···O3 in the order of 2.853 (2) Å. These interactions eventually lead to the formation of polymeric chains of the complex along the c-axis, as illustrated in Figure 2.

Weaker intermolecular hydrogen bonding was also noted between C13—H13···O1ii in the order of 3.487 (2) Å and C32—H32B···O1i in the order of 3.360 (3) Å.

Experimental top

V2O5 (1.0 g, 5.5 mmol) was added to a mixture of ethanol, water and sulfuric acid (5 cm3, 2 cm3 and 2 cm3 respectively) and refluxed for one hour, after which the yellow mixture turned a brilliant blue colour. A solution of 1,3-diphenylpropane-1,3-dione (4.93 g, 22 mmol) in ethanol (10 cm3) was added to the reaction mixture which was then stirred for ca 10 min. A saturated solution of sodium carbonate in water (20 cm3) was added to the mixture and the resulting green precipitate was collected by filtration. The precipitate was recrystallized from methanol and, after two weeks, small red needle-like crystals of [VO(dbm)2(MeOH)] were formed (yield: 2.35 g, 70%).

Refinement top

The methyl and aromatic H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.95 and 0.98 Å and Uiso(H) = 1.5Ueq(C) and 1.2Ueq(C), respectively. The hydrogen atoms of the methine groups, the methanol hydroxyl groups as well as the H atoms on C32 were located on the Fourier difference map and refined isotropically. The highest residual electron density was located 0.54 Å from H31C and the deepest hole was 0.68 Å from V1.

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
