Abstract
Ca0.1667Na3.6667FeP2O8F (P3OBAR, a = 13.723(2) angstrom, c = 6.879(1) angstrom, Z=6, V=1121.8(3) angstrom3) was prepared by the flux techniq ue. The structure was solved by single crystal methods using 1493 obse rved reflections (R=0.031, R(w)=0.041). The structure consists of octa hedrally coordinated Fe atoms alternating with sodium octahedra along the c-axis. A majority of sodium ions and the Ca ions are located in r ather restricted one-dimensional tunnels running along the c-axis.
