| Abstract: | Na11CuO4]SO4]3 was obtained from a redox reaction of CuO with Na2O2 in the presence of Na2O and Na2SO4 in sealed Ag containers under Ar atmosphere at 600°C. The crystal structure has been determined from X-ray single crystal data at 293 and 170 K (Pnma, Z=4). The lattice parameters have been refined from X-ray powder data at 293 K as well: a=1597.06(6) pm, b=703.26(3) pm, c=1481.95(6) pm. The structure contains isolated distorted square-planar CuO4]5− anions and non-coordinating sulfate groups. Furthermore, we report calculations of the Madelung Part of the Lattice Energy (MAPLE) and some of the physical properties of Na11CuO4]SO4]3. |
