Synthesis and Structural Characterization of Zinc Complexes with Sulfonamides containing 8‐Aminoquinoleine

Sulfonamides obtained by reaction of 8‐aminoquinoline with benzenesulfonyl, toluene‐4‐sulfonyl and naphthalene‐2‐sulfonyl chlorides have been used to synthetize coordination compounds with Zn^II with a ZnL₂ composition. Determination of the crystal structures for the resulting complexes by X‐ray diffraction shows a distorted tetrahedral environment for the Zn²⁺ ions, sulfonamides acting as bidentate ligands through the nitrogen atoms from the sulfonamidate and quinoline groups. FT‐IR, ¹H and ¹³C NMR and mass spectra of these compounds are also discussed.
