Popis: Ca 0.1667 Na 3.6667 FeP 2 O 8 (P 3 , a =13.723(2) A , Z =6, V =1121.8(3) A 3 ) was prepared by the flux technique. The structure was solved by single crystal methods using 1493 observed reflections (R = 0.031, Rw=0.041). The structure consists of octahedrally coordinated Fe atoms alternating with sodium octahedra along the c-axis. A majority of sodium ions and the Ca ions are located in rather restricted one-dimensional tunnels running along the c-axis.
