The new erbium(III) complex of picolinic acid (Hpic), ["Bu4N][Er(pic)(4)].5.5H(2)O, was synthesized and the crystal structure determined by single-crystal X-ray diffraction. The compound was further characterized using IR, Raman, H-1 NMR and elemental analysis. The picolinate ligands (pic(-)) are coordinated through N,O-chelation to the erbium cations, as shown by X-ray diffraction and spectroscopic results, leading to an eight coordinate complex. Photoluminescence measurements were performed for this compound which exhibits infrared emission. (C) 2003 Elsevier B.V. All rights reserved.
