Abstract top

In the title complex, [Hg2I4(C26H20FOP)2], the HgII centre is four-coordinate with one short Hg-I bond [2.6895 (7) Å], one Hg-C bond and two asymmetric bridging Hg-I bonds with distances of 2.7780 (8) and 3.2599 (8) Å. The title molecule has a crystallographic inversion centre at the centroid of the four-membered ring formed by the two Hg atoms and two I atoms. The crystal packing is stabilized by C-H...O hydrogen bonds.

Comment top

The dimeric structure adopted by complexes is in contrast to the O-coordinated trinuclear mercury (II) complex of the phosphorusylide Ph3PCHCOPh (Kalyanasundari et al., 1999), but is similar to the structure of trans-di-liododiiodobis (triphenyl phosphoniumcyclopentadienylide) dimercury(II) reported by Baenziger et al. (Baenziger et al., 1978) and the C-coordinated dinuclear mercury(II) halide complexes of Ph3CHCOPh(BPPY) (Kalyanasundari et al., 1995). The C-coordination of FBPPY is in stark contrast to the O-coordination of the phosphorus ylide, Ph3PC(COMe)(COPh) (ABPPY), to a HgII centre (Laavanya et al., 2001). The difference in coordination mode between ABPPY and FBPPY to HgII can be rationalized in terms of the electronic properties and steric requirements of the ylides. The nucleophilicity of the carbanion in ABPPY is less than for FBPPY; this is due to the additional delocalization of the ylide electron density in ABPPY which is facilitated by the second carbonyl group. This will reduce the ability of ABPPY to bind via the ylidic carbon. Belluco et al. have studied steric influences on the coordination modes of ylide molecules to Pt(II) systems (Belluco et al., 1996). These authors concluded that the preferred coordination mode is via the ylidic carbon, but that steric hindrance around the metal centre or the ylidic carbon will necessitate O-coordination. Indeed, this trend is reflected here, both BPPY and FBPPY are slightly less sterically demanding than ABPPY, and both are C-coordinated to HgII.

The title molecule has a crystallographic inversion symmety in the mid-point of the four-membered ring formed by the two Hg atoms and two I atoms (Fig.1). The crystal structure of the title complex reveals that the HgII centre forms four close contacts with sp3 hybridization and has a 4-coordinate environment with one short Hg—I bond 2.6895 (7), one Hg—C bond and two asymmetric bridging Hg—I bonds at distances of 2.7780 (8) and 3.2599 (8) Å in complex [[{HgI2(FBPPY)}2]. The significant shortening of the Hg—C bond length, 2.281 (5) Å compared to analogous distances in [(C6H5)3PCHCOC6H5HgI2]2 (Kalyanasundari et al.,1995) and in [(C5H4P(C6H5)3HgI2]2 (Holy et al., 1976) [2.312 (13) and 2.292 (8) Å, respectively] must be attributed to the use of mercury orbitals with high s character for bonding to the ylidic carbon. The use of non-equivalent hybrid orbitals with high s character to bond to low electronegative atoms was proposed by Bent in the concept of isovalent hybridization to account for the variation in bond lengths and bond angles around a central atom (Bent, 1961). The terminal Hg—I bond length, 2.7780 (8) Å is comparable to 2.615 Å observed in the case of Hg2l4(ABPPY)2, which has a tetrahedral coordination environment around mercury with a bridging structure (Laavanya et al., 2001). The two bridged Hg—I bonds fall within the range 2.778 - 3.25994 Å reported for other structures (Laavanya et al., 2001) containing chloro bridged mercury. The angles around mercury vary from 94.17 (2) to111.82 (2) for I—Hg—I, a very distorted tetrahedral environment. This distortion must be due to the higher s character of the sp3 hybrid mercury orbitals involved in the above bonds and the formation of a strong Iodo bridge between the Hg atoms which requires the internal I—Hg—I angle to be considerably smaller. The stabilized resonance structure for the title ylide is destroyed by the complexes formation. On the other hand, the bond length of P(1)—C(19) in the similar ylide is 1.706 Å (Uson et al., 1985) which shows that the above bond is considerably elongated to 1.787 (6) Å in complex [{HgI2(FBPPY)}2]. The adaptation of dimeric structur in HgII ylide complex may be explained by both the preference of HgII to four coordination and the stability of the 18 electron configuration around HgII.

Experimental top

To a chloroform solution (15 ml) of triphenylphosphine (1 mmol) was added 2-bromo-4-fluoroacetophenone (1 mmol) and the resulting mixture was stirred for 12 h. The solution was filtered off, and the precipitate washed with diethyl-ether and air-dried. Further treatment with aqueous NaOH solution (0.5M) led to elimination of HBr, giving the free ligand precursors FBPPY. To a solution of FBPPY (0.100 g, 0.25 mmol) in acetone (5 ml) was added mercury (II) iodide (0.114 g, 0.25 mmol). The mixture was stirred for 12 h. On concentration by removing the solvent by vacuum, a pale yellow precipitate was obtained. The products were washed with benzene and dried in vacuo. Yield: 81%, M.p. 214 °C. Analysis calculated for C52H40F2Hg2I4O2P2:C 36.6, H 2.4%. Found: C 36.45, H 2.3%, 1H NMR: 4.62(d, 1H, CH, 2JPH= 5.5 Hz), 7.1–8 (m, 19H, Ph) p.p.m. and 31P NMR: 20.34 p.p.m. (Karami, 2007).

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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.
