Abstract
The reaction of 3-(2,4-dicarboxyphenyl)-2,6-pyridinedicarboxylic acid (H(4)dppd) with rare earth nitrates under hydrothermal conditions generated a series of new two-dimensional (2D) coordination polymers, namely {[La(Hdppd)(H2O)(2)center dot(H2O)(2)](n) (1), [Ln(2)(Hdppd)(2)(H2O)(4)center dot(H2O)(3)](n) [Ln = Sm (2), Eu (3)] and [Ln(Hdppd)-(H2O) (3)center dot H2O](n) [Ln = Gd (4), Tb (5), Dy (6), Ho (7), Er (8)] [Hdppd = 3-(2,4-dicarboxyphenyl)-2,6-pyridine-dicarboxylic trivalent anion]}. The complexes were characterized by X-ray single-crystal diffraction, infrared spectroscopy, elemental analysis and thermogravimetric analysis. Luminescence spectroscopy of 3 and 5 showed bright red and green luminescences due to the 4f(n)-4f(n) transitions in Eu3+ and Tb3+ respectively, although the luminescence lifetime is shortened by non-radiative decay due to the presence of coordinating water molecules. The magnetic properties of 2-8 were measured and discussed. Compound 6 exhibits frequency dependent out-of-phase signals, and ferromagnetic coupling exists in 8.
