Abstract
Novel unexpected coordination polymer [Tb(PHTHGLY)(CBGLY)(H 2O) 2](H 2O) 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 Tb 3+-complex crystallizes in a triclinic crystal system and space group P 1 ¯ , forming a 1D polymer where carboxylate groups bridge the Tb 3+ ions. The photoluminescence data revel that the ligands act as efficient “antennas” sensitizing the luminescence of the Tb 3+ ion showing a strong green emission color arising from intraconfigurational 5D 4 → 7F J transitions ( J = 0–6).
