(Received 17 January 2011; accepted 18 January 2011; online 29 January 2011)

In the centrosymmetric dinuclear title compound, [Pb₂(C₁₀H₆NO₂)₂(CH₃COO)₂(C₂H₅OH)₂], one O atom of the carboxylate group of the quinoline-2-carboxylate anion connects the two Pb^II atoms. The Pb^II atom is surrounded by four O atoms and one N atom in a Ψ-octahedral PbO₄NE geometry (E is the electron lone pair). Two longer Pb⋯O interactions distort the geometry towards a Ψ-square-antiprism. Intermolecular O—H⋯O hydrogen bonds link the molecules.

Comment top

A previous study of the methanol adduct of the title dinuclear compound, [Pb(C₁₀H₆NO₂)(C₂H₃O₂)(CH₃OH)₂]₂, has found a Ψ-octahedral geometry for the lead(II) atom. Two longer Pb···O interactions distort the geometry towards a Ψ-square-antiprism (Mohammadnezhad et al., 2010). Replacing the methanol solvent system by ethanol leads to the analogous ethanol adduct (Scheme I, Fig. 1), which has a similar structure.

Experimental top

Lead(II) acetate (1 mmol) and quinoline-2-carboxylic acid (1 mmol) were loaded into a convection tube; the tube was filled with dry ethanol and kept at 333 K. Colorless crystals were collected from the side arm after several days.
