Complexes Supported by Bidentate Ligands with a Delocalized Bond System

4 Complexes Supported by Bidentate Ligands with a Delocalized Bond System [Pg.15]

Interestingly, solid-state structure investigations on methyl thiosalicylate dialkylaluminum compounds uncovered close intermolecular S - C(ti) contacts (with an average S - C distance of 3.382 A significantly below the sum of the corresponding van der Waals radii [76, 77]) between the Al-S thiolate units and the ester component (28, Fig. 9) that can effectively compete with the putative sulfur-aluminum hypercoordinate bond (27, Fig. 9) [141]. The latter results provide the first evidence for the competition of intermolecular n Ti interactions, involving the thiolate sulfur atom and the electrophilic ester carbon atom, with the hypercoordinate bond in metal complexes it opens up an interesting area for further studies. [Pg.15]
