RbMn₆(As₂O₇)₂(As₃O₁₀): a new manganese(II) arsenate

B. Ayed, A. H. Abbdallah and A. Hadded

Abstract: Single crystals of rubidium manganese arsenate, RbMn₆(As₂O₇)₂(As₃O₁₀), have been prepared by a solid-state reaction at 1173  K. The compound crystallizes in the monoclinic system, space group P2₁/m. The structure consists of a complex network of edge-sharing MnO₆ octahedra, forming folded layers that are linked together by As₂O₇ and As₃O₁₀ groups, which is highly unusual. This arrangement delimits a tunnel parallel to the a-axis direction which accommodates Rb⁺.
