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.

The title complex, [Sr(C 68 H 106 O 16 )(H 2 O)], forms a pseudo-centrosymmetric monomer complex, in which one aquo (or water) ligand bridges three O centres of the first lasalocid anionic ligand (Lasa 2) and in which this ligand is tridentate and bonded to just one Sr atom, and the other lasalocid ligand (Lasa 1) is pentadentate and bridges the Sr centre within the monomer. The monomeric unit is stabilized by intramolecular C⎯H O and O⎯H…O type-hydrogen bonding interactions.
