title: Synthesis, crystal structure and luminescent property of complex [Tb0.1Gd0.9(TPTZ)(H2O)6]Cl(3).3H2O.
abstract: The complex [Tb0.1Gd0.9(TPTZ)(H2O)6]Cl(3).3H2O was prepared through the reaction of 2,4,6-tris-(2-pyridyl)-1,3,5-triazine (TPTZ) with TbCl3:GdCl3 (0.1:0.9) in absolute ethanol at room temperature. Single crystal X-ray diffraction revealed that the metal atom is nine-coordinated with three nitrogen atoms from one TPTZ ligand and six oxygen atoms from six water molecules. The complex emits intense green fluorescence under ultraviolet light. The luminescence peaks correspond to the characteristic emission 5D4-->7FJ (J=3-6) transitions of the Tb3+ ion.
