AgReO 4 nanoplates and micron‐sized AgReO 4 rods and stars are obtained for the first time from controlled particle growth in THF. [NBu 4 ][ReO 4 ] or [NMe 4 ][ReO 4 ] and Ag(OTf) (OTf: triflate) are used as the starting materials. The crystal growth is directed by the presence (i.e., plates) or absence (i.e., rods, stars) of trioctylphosphine (TOP) as a coordinating agent as well as by the temperature of the reaction (i.e., plates, rods in refluxing THF; stars at room temperature). Altogether, the growth of the respective morphology can be attributed to the availability and diffusion rate of dissolved Ag + that is influenced by the reaction temperature and the presence of TOP. The differently shaped AgReO 4 particles are characterized by scanning electron microscopy (SEM), X‐ray diffraction analysis (XRD), and Fourier‐transform infrared (FT‐IR) spectroscopy.
