Structure and applications of organotin complex based on trimethyltin cation and quinaldic acid

Abstract

The reaction between aqueous solution of Me3SnCl and acetonitrile solution of quinaldic acid (quinH) at room temperature affords a new organotin complex, [Me3Sn(quinH)(quin)]⋅6H2O (1). Complex 1 was structurally characterized using infrared, UV–visible and NMR spectra, thermogravimetric analysis and single‐crystal X‐ray analysis. The network structure of 1 is developed by a limitless number of discrete mononuclear molecules forming a one‐dimensional chain via hydrogen bonds. Extensive hydrogen bonds and π–π stacking associate the one‐dimensional chains creating a two‐dimensional array. The two‐dimensional arrays are additionally associated via hydrogen bonds through the water molecules and the methyl groups forming a three‐dimensional network. The cytotoxic impact of 1 on the viability of MCF‐7 cells was also examined using MTT assay, exhibiting great inhibiting action against MCF‐7 cells. Furthermore, the catalytic degradation performance of 1 towards methylene blue dye in the presence of H2O2 as oxidant was investigated. The reaction is first order with respect to methylene blue dye.
