摘要:
Two new cadmium diphosphonate complexes, namely, Cd-2(H2O)(2)[(C5H5N)CH2C(OH)(PO3)(PO3H)](2) 1 and Cd-2(H2O)(Cl)[(C5H5N)CH2C(OH)(PO3)(2)] 2, based on [1-hydroxy-2-(3-pyridyl)-ethylidenel-bis-[phosphonic acid] monosodium salt have been synthesized under hydrothermal reaction and characterized by single crystal X-ray diffraction. Both complexes show strong fluorescence emission in contrast to the free ligand, respectively, in solid state at ambient temperature. (C) 2008 Published by Elsevier B.V.
