A novel copper(II) ethyl bisulfate complex [Cu(Him)4(Eb)2] 1 (Him = imidazole, Eb = ethyl bisulfate) has been prepared and characterized by means of elemental analysis, IR and ESR. The structure was determined by single crystal X-ray diffraction analysis, which suggests that compound 1 exhibits a two-dimensional supramolecular structure through hydrogen bonds. Compound 1 displays strong third-order non-linear optical (NLO) absorption and refraction with absorption coefficient _2 1.10_10-11 m_w-1 and refractive index n2 5.60_10-16m2_w-1. The third-order non-linear optical susceptibility _(3) of compound 1 is 3.07_10-10 esu.
