Abstract

Tin(II)4-nitrophenoxide complexes with the formulas SnCl(OC₆H₄NO₂-4) and Sn(OC₆H₄NO₂-4)₂ were prepared through the reaction of stannous chloride (SnCl₂) with 4-nitrophenol (HOC₆H₄NO₂-4) in 1:1 and 1:2 molar ratios, respectively. The reaction was performed in tetrahydrofuran (THF) with diethylamine serving as the base. The resulting compounds were characterized through elemental analysis, determination of molecular weight, molar conductance measurements, and spectroscopic methods including IR and ¹H NMR spectroscopy. Current investigations are directed toward assessing the stability of these complexes and examining their potential antimicrobial activity. This study enhances insight into the coordination characteristics and reactivity of tin(II) with organic ligands, thereby contributing to the progress of coordination chemistry and its practical applications. The synthesized complexes were obtained in good yield under controlled experimental conditions and appeared as stable colored solids with appreciable solubility in common organic solvents. Infrared spectral data confirmed the coordination of the phenolic oxygen atom to the tin center through noticeable shifts in the characteristic stretching frequencies of the nitrophenoxide ligand. Proton NMR analysis further supported the proposed structures by displaying expected aromatic proton resonances corresponding to the coordinated ligand environment. Molar conductance values indicated the non-electrolytic nature of the complexes, suggesting that the compounds exist as neutral species in solution. The observed analytical and spectral findings collectively support the formation of monomeric tin(II) complexes with probable distorted coordination geometries around the metal center. These findings provide a useful basis for further exploration of organotin derivatives in synthetic and biological applications.

Keywords: Tin(II) aryloxides, 4-nitrophenol, reactivity, NMR, IR spectra
