Single-crystal growth of silver antimony sulfide (AgSbS < inf > 2 < /inf > ) nanostructure was successfully synthesized using AgNO3, Sb(CH < inf > 3 < /inf > CO < inf > 2 < /inf > ) < inf > 3 < /inf > and Na < inf > 2 < /inf > S < inf > 2 < /inf > O < inf > 3 < /inf > .5H < inf > 2 < /inf > O dissolved in propylene glycol under a cyclic microwave radiation without the use of any template at 600 W. Phase morphology and vibration mode of the as-synthesized product were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). In this research, AgSbS < inf > 2 < /inf > single-crystalline nanostructure was detected. Calculated direct energy gap of AgSbS < inf > 2 < /inf > is 1.75 eV, determined by UV-visible absorption.
