Abstract |
Tetrazole is known as one of promising ligands due to its diverse coordination ability to late transition metals such Mn, Cu, and Zn. The tetrazolyl ligand could act as a mono-, bi-, or tetradentate bridging ligand with transition metals, resulting in the formation of high dimensional coordination polymers. The tetrazole with a widely spread π-conjugation all around the molecule could promote complicated molecular assembly via electron donation of four nitrogen atoms towards the metal center and help the stabilization of the cationic metal center. For several years, our group has been interested in chelating tetrazolyl ligands to produce complicated molecular systems. For the better binding ability and stability, 5-(2-hydroxyphenyl)tetrazole was prepared and used as ligands in the complexation with various metal precursors including Ti, Zn, Cu, Ni, Fe. Ru and Ir metal centers. Especially, Fe complexes constitute novel examples of Fe scorpionate complexes. Additional metal exchanges with Ti were also observed. Ru and Ir supramolecules provided interesting structural features. In this presentation, we will discuss the structural diversity of metal tetrazolyl system.
