摘要：
Novel unexpected coordination polymer [Tb(PHTHGLY)(CBGLY)(H2O)(2)](H2O)(3) complex containing simultaneously N-phthaloylglycinate and N-(2-carboxybenzoyl)glycinate ligands has been prepared and characterized by single crystal X-ray structure, thermogravimetric analysis and infrared spectroscopy. The X-ray crystal diffraction indicates that the Tb3+-complex crystallizes in a triclinic crystal system and space group P (1) over bar, forming a 1D polymer where carboxylate groups bridge the Tb3+ ions. The photoluminescence data revel that the ligands act as efficient "antennas" sensitizing the luminescence of the Tb3+ ion showing a strong green emission color arising from intraconfigurational D-5(4)-> F-7(J) transitions (J = 0-6).
