Abstract
Abstract Herein we describe the syntheses of 4-(2-nitrophenylsulfonamido)benzoic acid (HL), and its tri-n-butyltin(IV) complex, Bu3SnL. The compounds were characterized by elemental analyses, FT-IR, 1H NMR, 13C{1H} NMR and X-ray diffraction. For the complex 119Sn{1H} NMR and 119Sn Mossbauer spectroscopies were also employed. The Bu3SnL is a monomer in the solid and solution states but exists as a polymer in the crystalline structure. The complex adopted distinct geometries, being tetrahedral in solution and intermediate between tetrahedral and trigonal bipyramidal in the solid state. Crystal structure determination of Bu3SnL revealed a bipyramid-trigonal geometry around the metal center, and the presence of a polymeric structure sustained by carboxylate bridges. Interconnections in the crystal structures were analyzed using Hirshfeld surfaces. The 2D-fingerprint plots indicated that the O H/H O interactions are more frequent in the HL·H2O crystal packing (44.9%) than in the Bu3SnL (26.8%).
