【 摘 要 】

Thermal decompositionof [Bu4N]2[Zn(imnt)2] and [M(NH3)2(imnt)]complexes with M = Zn and Cd, and imnt = (bis 1,1-dicyanoethylene-2,2 dithiolate)in inert atmosphere was investigated by thermogravimetric analysis (TG) anddifferential scanning calorimetry (DSC). Pyrolysis studies at different temperatures,300, 400, 500, and 600 ºC, in N2 atmosphere wereperformed and the products were characterized by X-ray diffraction (XRD), infraredand Raman spectroscopy, and scanning electron microscopy (SEM). The productswere identified as sulfide sub-micron particles, along with amorphous carbon.Particle sizes estimated by SEM were ca. 50 nm for the cationic complexesand 500 nm for the neutral complexes.
