A 3-Fold-Symmetric Ligand Based on 2-Hydroxypyridine: Regulation of Ligand Binding by Hydrogen Bonding
摘要:
A tripodal ligand based on 2-hydroxypyridine is presented. Cu-Cl adducts of H(3)thpa with Cu-I and Cu-II provide complexes featuring highly directed, intramolecular hydrogen-bonding interactions. An upper limit for the hydrogen-bonding free energy to Cu-I-Cl was estimated at 18 kcal/mol.

Nitritereduction by a copper complex featuring a proton-responsive tripodal ligand is demonstrated. Gaseous nitric oxide was confirmed as the sole NOX by-product in quantitative yield. DFT calculations predict that nitritereduction occurs via a proton and electrontransfer process mediated by the ligand. The reported mechanism parallels nitritereduction by copper nitrite reductase.
