Noncovalent interactions between stacked aromatic ligands on adjacent molecules in 7 and 8 produce one-dimensional chains in the crystal. Molecules 1-3 fail to produce crystalline, one-dimensional chains with covalent metal-organic bonding on reaction with Cu(II) alone. System 5, which contains a single acac ligand and a pyridyl nitrogen, forms a crystalline, one-dimensional chain on reaction with Cu(II) in the presence of a bidentate nitrogen ligand (9). The covalent bonding ribbon of the chain passes from acac to Cu(II) to the pyridyl nitrogen and back to acac. The phenanthroline ligands in 9 provide noncovalent bonding with adjacent chains in the crystal to produce a two-dimensional layered structure.

Lambert and Zhongqiang Liu Two acetylacetonate ligands separated by an aromatic spacer react with Cu(II) in the presence of bidentate nitrogen ligands to form crystalline, capped, dinuclear (zero-dimensional) structures, whereas acetylacetonate linked to pyridine forms a crystalline, one-dimensional chain on reaction with Cu(II) with phenanthroline ligands on adjacent chains noncovalently bonded to form a two-dimensional layered structure in the crystal.
