Abstract
The reaction of aqueous/acetonitrile solutions of Me3SnCl and 2,6-pyridinedicarboxylic acid (2,6-pydcH(2)) affords a new organotin complex, [Me3Sn center dot(2,6-pydcH)]center dot H2O, 1. The structure of 1 was characterized by IR. UV-Vis, TGA, NMR spectra, cyclic voltammetry and X-ray single crystal analysis. The network structure of 1 is constructed by an infinite number of discrete binuclear molecules forming 1D-chains via H-bonds. The extensive H-bonds and pi-pi stacking connect the 1D-chains, creating a 2D-array. The 2D-arrays are further connected by H-bonds via the water molecules and methyl groups, forming a 3D-network. The cytotoxic effect of 1 on the viability of MCF-7 cells was also determined by an MTT assay. The organometallic complex 1 has potentially good inhibition activity for MCF-7 cells.
