A Facile Synthesis of Organotin(IV) Carboxylates: Application as Single Source Precursor for Deposition of Tin Oxide Thin Films and Evaluation of Biological Activities

Abstract

AbstractHerein, we report synthesis of novel organotin(IV) carboxylates i.e; [(C6H5)3Sn(C10H14NO3)] B1 and [(C4H9)3Sn(C10H14NO3)] B2 by reacting triphenyltin hydroxide and bis(tributyltin) oxide with as‐prepared ligand 3‐cyclohexylcarbamoyl‐acrylic acid A under inert atmosphere. The as‐synthesized complexes were characterized by elemental analysis (CHNS), fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy(1H‐NMR, 13C‐NMR) and mass spectrometry (EI‐MS). The structures of both as‐prepared tin complexes B1 and B2 were determined by single crystal X‐ray crystallography. Thermogravimetric analysis has shown single step decomposition of both these complexes. The as‐prepared complexes were used as single source precursor for the deposition of tin oxide thin films at 350 °C and 400 °C by aerosol assisted chemical deposition (AACVD) on bare and at 400 °C on carbon nanodots pre‐coated glass substrate. The as‐deposited thin films were characterized by powdered X‐rays diffraction (pXRD), field emission scanning electron microscope (FE‐SEM) and energy dispersive X‐rays spectroscopy (EDX). Furthermore, antimicrobial, anti‐oxidant and cytotoxicity studies of both complexes showed moderate to good biological activities. Thus, as‐prepared novel complexes have potential applications in materials as‐well as in medicinal chemistry.
