Na₅Bi₂(AsO₄)(As₂O₇)₂

Pentasodium dibismuth arsenate bis(diarsenate) has been synthesized by solid-state reaction and characterized by single-crystal X-ray diffraction. The structure is a three-dimensional framework comprising distorded BiO₆ octahedra, As₂O₇ groups and AsO₄ tetrahadra sharing corners. Along the c axis, the structure exhibits large tunnels where Na⁺ cations are located.
