Sažetak
β-diketonate ligands (i.e. acetylacetone, α -benzylacetylacetone and dibenzoylmethane) were used to prepare coordinatively unsaturated MII-betadiketonate complexes (where MII = CuII, NiII, CoII). It has been previously shown that this class of compounds exhibit the intriguing ability to act as hosts for both small and bulky molecules (e.q. solvent molecules and fullerenes). [1] In addition, metal(II)-betadiketonates were recently recognized as building blocks for 1D hydrogen-bonded coordination polymers. [2, 3] In particular, β-diketones were used as chelating ligands for CuII, CoII and NiII to direct their self-assembly process with ditopic molecular linkers towards the formation of 1D polymers. In this contribution the design, synthesis and structural analysis of 2D hydrogen-bonded structures based on infinite 1D coordination polymers, which are composed of metal(II)-betadiketonates (where MII = CuII, NiII, CoII) and small polyfunctional ligands such as hexamethylenetetramine, pyrazine, 4, 4'-bipyridine, nicotinamide and pyridine will be described. Specifically, it will be shown how an appropriate polyfunctional ligand can orchestrate the self-assembly process of 1D coordination polymers into 2D hydrogen-bonded networks. The structural analysis was performed via single-crystal X-ray diffraction. [1] D. V. Soldatov, J. Chem. Cryst. 36 (2006) 747-768. [2] C. B. Aakeröy, N. Schultheiss & J. Desper, Inorg.
