Synthesis, Crystal Structure and Spectroscopic Analysis of a New Sodium Coordination Polymer

Abstract

A new sodium coordination polymer, [Na2(L)2(H2O)4]n (1), was synthesized by reflux reaction of p-aminobenzene sulfonic acid, p-hydroxy benzaldehyde and NaOH in ethanol/water solution and characterized by elemental analysis, UV-vis, IR and X-ray single crystal diffraction analysis. The crystal of 1 belongs to monoclinic, space group P21/c with a = 17.765(4) Å, b =10.181(2) Å, c = 8.0450(16) Å, β = 91.67(3)°, V = 1454.5(5) Å3, Z = 4, Dc = 1.531 mg·, μ = 0.28 mm-1, F(000) = 696, and final R1 = 0.0327, ωR2 = 0.0854. The molecules of 1 are extended to a 2D layer structure along ab plane. The 2D layers form 3D framework structure by the interaction of π-π stacking and hydrogen-bond interaction.
