Abstract

<p>Using semiempirical MNDO method of quantum chemistry the optimal geometries and corresponding electronic structures of [Pb<sub>3</sub>(OH)<i><sub>n</sub></i>]<sup>6-<i>n</sup></i> model systems as well as of their hydrated [Pb<sub>3</sub>(OH)<sub><i>n</i></sub>(H<sub>2</sub>O)<sub>8-<i>n</i></sub>]<sub>6-<i>n</i></sub> analogues (n = 4, 5) are investigated. The most stable trinuclear lead(II) complexes present in aqueous solutions correspond to <i>cyclo</i>-(μ<sub>3</sub>-OH)(μ<sub>2</sub>-OH)<sub>3</sub>Pb<sub>3</sub><sup>2+</sup>, Pb(μ-OH)<sub>2</sub>Pb(μ-OH)<sub>2</sub>Pb<sup>2+</sup>, <i>cyclo</i>-(μ<sub>3</sub>-OH)<sub>2</sub>(μ<sub>2</sub>-OH)<sub>3</sub>Pb<sub>3</sub><sup>+</sup>, Pb(OH)(μ-OH)<sub>2</sub>Pb(μ-OH)Pb(OH)<sup>+</sup> and Pb(OH)(μ-OH)<sub>2</sub>Pb(μ-OH)<sub>2</sub>Pb<sup>+</sup> systems. The key role of OH bridges (by vanishing direct Pb-Pb bonds) on the stability of individual isomers is discussed.
