Bis(acetyl­acetonato)oxido(triphenyl­phosphine oxide)vanadium(IV)

Abstract

In the structure of the title compound, [V(C5H7O2)2O(C18H15OP)], the V atom adopts a slightly distorted octa­hedral geometry with its coordination completed by four O atoms of two acetyl­acetonate (acac) ligands, one oxo group and one O atom of the triphenyl­phosphine oxide (OPPh3) ligand.

Comment

The crystal consists of monomeric units of VO(acac)2(OPPh3) packed together without contact significantly shorter than the sum of the van der Waals radii. Each V center is six-coordinated by four O atoms of two acac ligands, one oxo group and one O atom of OPPh3 ligand to furnish a slightly distorted octahedral geometry. The four acac O atoms define the equatorial plane. The oxo group and the O atom from OPPh3 ligand occupy the axial sites in a trans configuration. The V—O(acac) bond distances [1.9974 (13) Å-2.0085 (14) Å] are a little longer than those observed in [VO(acac)2] [1.966 (6) Å-1.986 (6) Å, Shuter et al., 1995; Hoshino et al., 2005] and the bond length of V—O(OPPh3) is 2.2586 (13) Å, significantly longer than those found in [VOCl2(OPPh3)2] [1.986 (5) Å and 2.002 (5) Å, Caira & Gellatly, 1980] and [VCl3(NPPh3)(OPPh3)](1.928 (6) Å, Rübenstahl et al., 1993).

The presence of OPPh3 ligand in the compound was unexpected since the original reactant was PPh3. It has been shown in earlier studies that some metal oxo-complexes might react with PPh3 to give rise to OPPh3 due to their catalytic and redox properties (Scott et al., 1992; Zhu et al., 1996; Mévellec et al., 2001). Thus, it was speculated that PPh3 was oxidized to OPPh3 by oxovanadium complex in this experiment.

Experimental

The title compound was obtained unintentionally when we attempted to synthesize vanadium coordination complexes containing 3,5-pyrazoledicarboxylato ligand (H3pdc). To the mixture of H3pdc (0.5 mmol), NaOH (1 mmol) and VO(acac)2 (0.5 mmol) in 10 ml H2O was added a CHCl3 solution (5 ml) of PPh3 (0.25 mmol). The resulting solution was allowed to stand at room temperature for six weeks to deposit green crystals of X-ray quality.

Refinement

H atoms bound to C atoms were located by geometry, and their positions and thermal parameters were constrained to ride on their parent atoms during the structure refinement.

Special details

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.
