| Abstract: | The tetra(o-eyanobenzyl)tin compound has been synthesized by the reaction of eyanobenzyl chloride with tin, and its molecular structure was characterized by elemental analysis,IR spectra, 1H NMR and X-ray diffraction. Crystal data for this compound: monoclinie, space group C2/c, M, = 583.24, a = 1.9629(2), b = 1.05967(13), c = 1.41249(18) nm, β = 118.180(2)°, V =2.5898(5) nm3, Z = 4, Dc =1.496 g/cm3, μ(MoKa) = 1.015 cm-1, F(000) = 1176, R = 0.0189, wR =0.0497 (observed reflections with Ⅰ 2σ(Ⅰ)) and R = 0.0218, wR = 0.0513 (all reflections).The molecular structure adopts a distorted tetrahedral geometry around the tin atom. The Sn…N weak interaction between the Sn and N atoms of cyano forms an intermolecular H-bonding, and the bond length is 0.3570 nm; the interaction between hydrogen of methylene and benzene ring of benzyl forms C-H…C with its bond length of 0.2817 nm; and the interaction among hydrogen of benzene ring and carbon of cyano forms Ph-H…C bond (0.2897 nm) of the σ…π interaction. A 3D chain structure is formed by the above weak intermolecular interactions. |
