摘要

A novel his (dmit) complex of copper (II), [(C3H7)(4)N](2)[Cu(dmit)(2)] (1), where dmit is 2-thioxo-1,3-dithiole-4,5-dithiolate, was prepared and structurally characterized by X-ray single crystal diffraction. The copper (11) atom is tetracoordinated by four dmit S atoms, forming a nearly square planar arrangement. The [Cu(dmit)(2)](2-) anions and the [(C3H7)(4)N](+) counter-cations form a three-dimensional solid-state structure by C-H...S hydrogen bonds. The third-order nonlinear optical properties of the complex were determined by picosecond Z-scan technique at a wavelength of 1064 nm. The results indicate the compound exhibits reverse saturation absorption and self-defocusing performance. The molecular second-order hyperpolarizability gamma is calculated to be as high as (1.8 +/- 0.2)x 10(-30) esu. (C) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
