In the title compound, [Re(C6H5N)3(CO)3]BF4, the ReI ion is six-coordinated by three pyridine N atoms and three carbonyl C atoms. In each case, the carbonyl C atom lies trans to a pyridine N atom. In the crystal, the ions are linked via C—H...F hydrogen bonds and C—H...π inter­actions, forming a three-dimensional framework. The F atoms of the BF4 anion are disordered over two positions and gave a final refined occupancy ratio of 0.705 (11):0.295 (11).

Comment top

Amoroso and coworkers (Amoroso et al., 2008) prepared a novel 3-chloromethylpyridyl bipyridine tricarbonyl rhenium complex and demonstrated the suitability of this complex in Mitochondria. That report represents the first application of a luminescent agent for specific targeting of a biological entity in imaging. Recently, Coogan and co-workers (Coogan et al., 2009) have also directed their research focus towards such complexes, thus preparing more novel rhenium tricarbonyl compounds to prove that heavy metals are not only erroneously termed as poisons, but can also be useful towards preparing drugs of great biological significance to man. Thus the design, syntheses and characterization of rhenium(I) tricarbonyl complexes has being of great interest due to their biological significance. The first report of the tricarbonyl tris-pyridyl rhenium(I) cation was published by Franklin et al. (2008), viz. tricarbonyl tris-pyridyl rhenium(I) hexafluorophosphate, which is quite similar to the title compound with some slight differences.

The molecular structure of the title complex is illustrated in Fig. 1. The ReI ion is six-coordinated by three pyridine N atoms and three carbonyl C atoms.

In the crystal, the ions are linked via C-H···F hydrogen bonds and C-H···π interactions forming a three-dimensional framework (Table 1).

Experimental top

The preparation of the title compound is illustrated in Fig. 2. [Re(C14H10N2O)(CO)3Br] (0.16 g, 0.28 mmol), prepared according to literature procedures (Al Subari et al., 2010; Coogan et al., 2009), was reacted with AgBF4 (0.05 g, 0.28 mmol) in 11 ml diethyl ether under nitrogen with refluxing for 35 min. The solution was then filtered through celite and to the clear filtrate pyridine (0.023 ml, 0.28 mmol) was added. The mixture was stirred for ca. 24 h. After it was poured into a vial and petroleum ether was added drop wise in excess to precipitate out the complex. This was covered with perforated foil and left overnight in the hood. Colourless block-like crystals grew on the sides of the vial.

Refinement top

C-bound H atoms were placed in idealized positions and refined using a riding model: C-H = 0.95 Å with Uiso(H) = 1.2Ueq(C). The F atoms of the BF4 showed significant elongation in the thermal ellipsoids suggesting disorder over two positions; final refined occupancy ratio = 0.705 (11):0.295 (11).

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.
