Synthesis and Crystal Structure of Sm（4-Pyta）3（H2O）2n （4-Pyta = 4-Pyridylthioacetate）

摘要

cqvip:A novel coordination polymer [Sm(4-Pyta)3(H2O)2]n has been synthesized by the hydrothermal reaction between 4-Pyta (4-Pyta = 4-pyridylthioacetate) and Sm(NO3)3. The structure was characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The crystal belongs to the triclinic system, space group P 1, with a = 9.100(2), b = 11.842(3), c = 12.183(3) , α = 79.781(4), β = 74.124(4), γ = 84.882(5)°, V = 1241.6(5) 3, Z = 2, Mr = 690.95, Dc = 1.84806 g/cm3, F(000) = 686, μ = 2.669 mm-1, the final R = 0.0388 and wR = 0.0808 for 4149 observed reflections with I > 2σ(I). The structural analysis shows that the complex exhibits a one-dimensional architecture. Intermolecular hydrogen bonding interactions are found in the complex molecules.
