Synthesis and characterization of a novel spring-like organotin complex containing guest benzene molecules

A novel spring-like organotin complex [(Ph(3)Sn)(C(7)H(5)ClNO(2))](n)center dot 3C(6)H(6) (1), has been synthesized by treatment of 6-chloro-3-pyridineacetic acid bis(triphenyltin) oxide on the condition of reflux. The complex was characterized by elemental analysis, FT-IR, NMR ((1)H, (13)C and (119)Sn) spectroscopy, and X-ray crystallography diffraction analysis. The structure analyses reveals that complex 1 is an 1D infinite chain linked by intermolecular Sn-O bonds, in which the guest benzene molecules are established in the cavity of this helical chain; all the tin atoms of complex 1 are five-coordinated.
