Abstract:

2-(Salicyloylhydrazone)propionic acid dibutytin complex was synthesized via the reaction of 2-(salicyloylhydrazone)propionic acid with dibutyltin oxide. The complex was characterized by IR, 1H NMR, 13C NMR spectroscopy, and elemental analysis. The crystal structure was determined to be a tetragonal system by single crystal X-ray diffraction. The crystal structure of the complex belongs to a centrosymmetric structure mode with a four-member central Sn2O2 unit, in which the central Sn atom is seven-coordinated in a distorted pentagonal pyramid configuration. The complex is stable below 103 ℃ according to thermal analysis. The interaction between the complex and Herring sperm DNA was studied by UV spectroscopy, ethidium bromide(EB) fluorescent probe and viscosity, and the results suggest the intercalation interaction between the complex and Herring sperm DNA.
