[XeF5](+)/Metal and [XeF5](+)/Non-Metal Mixed-Cation Salts of Hexafluoridoantimonate(V)

New types of [XeF5](+) salts, i.e., NO2XeF5(SbF6)(2) and XeF5[Cu(SbF6)(3)], are derived from reactions between XeF5SbF6 and NO2SbF6 or Cu(SbF6)(2), respectively. The crystal structure of the former consists of [NO2](+) and [XeF5](+) cations and [SbF6](-) anions. The main feature of the crystal structure of XeF5[Cu(SbF6)(3)] are rings of CuF6 octahedra that share apexes with SbF6 octahedra connected into an infinite tridimensional framework. This arrangement leads to the formation of cavities within which [XeF5](+) cations are located. Raman spectra of both [NO2](+)/[XeF5](+) and [XeF5](+)/Cu2+ mixed-cation hexafluorido-antimonates(V) are reported herein.
