Abstract

The synthesis, spectroscopic characterization, and X-ray crystal structure ofthe sodium salt of a new sulfonated water-soluble ligand, sodium 2-(2-pyridin-2-yl-ethylamino)-benzenesulfonate (L) are described. Compound L crystallizes in thecentrosymmetric space group Pbcn, orthorhombic, a=31.930(13) å, b=7.153(3) å,c=14.193(6) å, α=90.00, β=90.00, γ=90.00, V=3220(2) å3, Z=9. π−π stacking contactsinvolving interactions between the π-donor benzene and the π-acceptor pyridine systemsreinforce and direct the self-assembly of the structural motifs in the solid state.
