A binuclear copper(II) complex, isothiocyanato{2-[2-(dimethylamino)ethylthio]ethanolato}copper(II), (Cu(CH<SUB>3</SUB>-nso)NCS), was prepared and characterized by elemental analysis, infrared and electronic spectra, magnetic susceptibility (90–300 K), and single-crystal X-ray diffraction. The complex exhibits a band at 25×10<SUP>3</SUP> cm<SUP>−1</SUP> characteristic of alkoxo-bridged structure. The temperature dependence of the magnetic susceptibility is unusual and shows a dramatic change in the temperature range 240–180 K. The magnetic data were fitted to the Bleaney-Browers equation separately in the two temperature ranges (−2<I>J</I>=535 cm<SUP>−1</SUP> for 300≥<I>T</I>≥240 K; −2<I>J</I>=595 cm<SUP>−1</SUP> for 170≥<I>T</I>≥90 K).
