A novel copper(H) thiocyanate complex [Cu(im)(2)(NCS)(2)] 1 (im = imidazole) has been prepared and characterized by spectroscopic analysis and crystallographic method. This supramolecular compound exhibits a three-dimensional solid state structure constituted by N-(HS)-S-... hydrogen bonds and pi-pi stacking interactions. The compound in DMF solutions has a very strong third-order non-linear optical (NLO) behavior with absorption coefficient and refractive index alpha2 = 1-18 X 10(-11) m X w(-1), n(2) = -9.00 x 10(-16) m(2) w(-1), respectively, and third-order NLO susceptibility chi((3)) of 7.00 x 10(-10) esu.
