catena-Poly[[bis(pyridine)-lead(II)]bis(μ-penta-fluoro-benzene-thiol-ato)]

Area of Science:

• Inorganic Chemistry
• Materials Science
• Crystallography

Background:

• Lead(II) compounds are known for diverse coordination geometries.
• Organometallic complexes with fluorinated ligands offer unique properties.
• Understanding supramolecular assembly in lead complexes is crucial for materials design.

Purpose of the Study:

• To synthesize and characterize a new lead(II) complex with pentafluorophenylthiolate and pyridine ligands.
• To elucidate the coordination environment and solid-state structure of the title compound.
• To investigate the intermolecular interactions driving the observed polymeric structure.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
• The coordination geometry around the Pb(II) center was analyzed.
• Intermolecular lead-sulfur interactions were quantified.

Main Results:

• The title compound, [Pb(C(6)F(5)S)(2)(C(5)H(5)N)(2)](n), was synthesized and structurally characterized.
• The Pb(II) atom is in a ψ-trigonal bipyramidal S(2)N(2) bonding environment.
• Weak intermolecular Pb⋯S interactions (3.618(4) and 3.614(4) Å) lead to a 1D polymeric structure.

Conclusions:

• The study presents a novel lead(II) coordination polymer.
• The observed structure is dictated by axial pyridine coordination and equatorial thiolate/lone pair arrangement.
• Long-range Pb⋯S interactions are key to the formation of the extended 1D network.
