Abstract: Tungsten dioxo complex WO2(C9H6NO)2 was obtained via the low temperature solid-state reaction of(NH4)2WS4, 8-hydroxyquinoline(8-hq) and(CH3)4NI, and it was characterized by means of elemental analyses, IR spectroscopy and X-ray diffraction analysis. The crystal of the title compound belongs to monoclinic, space group C2/c, with the crystal cell parameters: a=1.3316(3) nm, b=0.94444(19) nm, c=1.3485(3) nm, β=109.66(3)°, V=1.5970(6) nm3, Z=6. The title compound possesses a supramolecular structure formed through hydrogen bonds and π-π stacking interactions. The third-order non-linear optical(NLO) properties of the title compound were also investigated. The third-order non-linear absorption coefficient α2 and refractive index n2 are 0.85×10-11 m/W-1 and -1.5×10-19 m2/W, respectively. The third-order non-linear susceptibility χ(3) is 3.03×10-13 esu for 3.8×10-5 mol/L sample concentration.
