Abstract: A one-dimensional dysprosium coordination polymer { [Dy(Sal) 3 (H 2 O) 2 ] 2 · H 2 O } n (Sal = 2- hydroxybenzoic acid) has been synthesized by a novel reaction from the hydrolysis process of O -acetylsalicylic acid. X-Ray analysis reveals that it forms one-dimensional chain-like structure through bridged oxygen atoms of carboxylate groups. The title coordination polymer crystallizes in the monoclinic system, space group C 2/ c , with lattice parameters a = 16.217(5) °A , b = 14.896(5) °A , c = 9.835(3) °A , β = 101.453(4) ◦ , V = 2328.4(13) °A 3 , D c = 1.857 Mg/m 3 , Z = 2, F (000) = 1280, GOF = 0.941, R 1 = 0.0281. The photophysical properties have been studied with ultraviolet absorption, excitation, and emission spectra.
