|Abstract:||A series of Ni2+ complexes of N-(7-hydroxy-4-methyl-8- coumarinyl)-glycine (H2mugly) and N-(7-hydroxy-4-methyl-8-coumarinyl) -l-alanine (H2muala) has been prepared by self-assembly of Ni(CH 3COO)2·4H2O with ligands in the presence of alkali metal ions. The complexes have been characterized by elemental analysis, thermogravimetry, IR and ESI-MS studies, and several of these complexes have also been structurally characterized by X-ray crystallography. Interestingly, the alkali metal ions have been found to direct the self-assembly processes and facilitate the formation of oligonuclear structures. Structural investigations showed that the molecular clusters displayed intriguing architectures including heptanickel metallocrowns with highly symmetrical hexagonal shapes, a heterobimetallic molecular cage and a pentanickel cluster with a nanobasket shape. The diversity of the coordination geometries and the cluster structures are discussed in detail. © 2010 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.|
