Comment top

Colourless, needle-shaped crystals of C26H21HgBr3OP were obtained from a mixture of methanol, dmso and diethyl ether. The crystal structure consists of discrete [BrC6H4COCH2PPh3]+ cations and [Hg2Br6]2- anions (Fig. 1). The crystals are air-stable and resistant to moisture. All atoms occupy general position in the monoclinic space group, P21/n. The site symmetry of the anion is -1, with the inversion centre halfway between the two Hg atoms. Comparison of the bond lengths and bond angles within the above crystal show that the phosphonium as a ligand is electrostatically under the influence of an anionic part of an bromomercurate in the unit cells (for instance the bond lengths C6—C7, O1—C7, C8—P1 and P1—C9 and bond angles C8—P1—C9, O1—C7—C8 are 1.489 (5), 1.213 (5), 1.804 (4) and 1.800 (4) A° and 106.7 (2) and 120.4 (4)° for title compound and 1.514 (2), 1.256 (2), 1.719 (2) and 1.805 (2) A° and 105.3 (1) and 123.2 (2)° for the phosphorane molecule (Sabounchei et al., 2007)). The bridging Hg—Br bond lengths in the crystal are 2.6693 (4) A° and 2.7920 (4) A°, the terminal Hg—Br distances are 2.5192 (5) A° and 2.5433 (5) A°. These values are well within the reported bond distances (2.703—-2.787 A° for bridging bromide and 2.479–2.532 A° for terminal bromide) in [Hg2Br6]-2 anions (Nockemann & Meyer, 2002; Thiel et al., 1994; Hu et al., 2003).

Experimental top

Starting materials were purchased from commercial sources and used without further purification.The title compound was prepared by addition of solution of HgBr2 (0.18 g, 0.5 mmol) in methanol (15 ml) to a solution of the 4-bromobenzoylmethylenetriphenylphosphorane (0.229?g, 0.5?mmol) in dry methanol (15 ml) and stirring for 12 h. A white product formed upon slow evaporation ofthe solvent. It was washed several times with dry diethylether and dried invacuo. The product was then washed with benzene and dried in vacuo. Yield 83%, m.p=290 K. It was recrystallized from a mixture of methanol, dimethylsulfoxide and diethyl ether (1:1:3).

Refinement top

All H atoms were positioned geometrically and refined using a riding model, Uiso=1.2Ueq of the respective carrier atom. The largest difference peak and hole (1.64 and -1.32 e.A-3) are found 1.18Å and 0.05Å respectively from Hg.

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.
