A new compound, 1,5-bis （2-hydroxy-3-methoxyphenylmethylene）-thiocarbohydrazone （1） （ C19H22N504S, Mr=416.48） has been synthesized and characterized by elemental analysis, IR UV and i H NMR. The crystal structure has been determined by X-ray single crystal diffraction. It crystallizes in the triclinic system, space group P1^- with lattice parameters a =0.9983（1） nm, b=1.0509（1） nm, c=1.0748（1） um, a=90.089（2）°,β=110.033（2）°,γ=103.069（2）°. The nonlinear optical property of the compound in DMF solution has been investigated by open-aperture Zscan technique at the wavelength of 532 nm. Crystallographic data of the structural analysis have been deposited with the Cambridge crystallographic data center： CCDC No. 240088.
