Crystal structure of a new polymeric thallium-lasalocid complex: lasalocide anion-thallium(I) containing aryl-Tl interactions

Abstract

The title complex, [Tl(C 34 H 53 O 8 )] n , forms a pseudo individual monomer complex, in which the anionic oxygen of carboxylate group serves to neutralise the charge of Tl + , the other five O centres of the first lasalocid anionic ligand (Lasa 1) and in which this ligand is pentadentate Oligand and bonded to a second Tl centre by using phenyl-metal coordination. A second lasalocid ligand (Lasa 2) is also pentadentate O-ligand and bridges the first Tl centre within the polymer. The monomeric unit is stabilized by strong intramolecular aryl-Tl type-metal half sandwich bonding interactions.
