摘要：

An original three-step method has been developed for the synthesis of a new polydentate 8-hydroxyquinoline ligand system with a 1,3-tropolone fragment at position 2 of the quinoline ring. X-ray diffraction structural analysis, H-1 and C-13 NMR spectroscopy, and quantum-chemical calculations showed that this ligand exists in the NH-tautomeric form with the phenolic hydroxyl group in the exo position of the quinoline ring.
