The hydrated tricyclohexyltin 4-pyridinecarboxylate complex was synthesized by the reaction of tricyclohexyltin hydroxide and 4-pyridinecarboxylic acid in ethanol solvent.The structure of the complex was characterized by elemental analysis,IR,1H NMR,differential thermal analysis and X-ray single crystal diffraction.The study on the complex has been performed with quantum chemistry calculation and in vitro anticancer activity.The results show that the complex is in a central tin pentagonal distorted triangular biconical configuration.The complex showed stronger inhibitory activity than cisplati...
