Poly[bis(μ-pentafluorobenzenethiolato)lead(II)]

Abstract

The title compound, [Pb(SC6F5)2]n, exhibits a layered structure containing two differently hexa­coordinated PbII atoms. One is situated on a centre of inversion and is coordinated by six S atoms, its valence lone pair of electrons being consequently stereochemically inactive. The other Pb atom is pyramidally coordinated by three S atoms and forms three contacts to adjacent F atoms, the stereochemically active lone pair pointing towards the F3 plane.

“…Further, the structure possesses no intramolecular Pb ••• F contacts such as those observed in [(F 5 C 6 S) 2 Pb] n (Fleischer et al, 2006).…”

“…However, the bonding environment at lead and the degree of intermolecular bonding may be altered via the introduction of Lewis base ligands that occupy metal coordination sites, see: Appleton et al (2004); Briand et al (2007). It has been shown that [(F 5 C 6 S) 2 Pb] n exhibits a three-dimensional framework structure containing hexacoordinated Pb II atoms (Fleischer et al, 2006). For van der Waals radii, see: Bondi (1964); Brown (1978).…”

“…Pb(SR F ) 2 : All lead thiolates were prepared by modification of previously published methods [32,33,34,35,36]: To a solution of Pb(CH 3 COO) 2 (5.2 mmol) in 100 mL water, thiol (HSR F ) (10.0 mmol) dissolved in about 10 mL of ethanol was added under vigorous stirring at room temperature. A white or yellow precipitate was rapidly formed.…”
