Two rht anionic metal–organic frameworks were synthesized. There are six [M(H₂O)₆]²⁺ ions held together by a super-strong H-bond and arranged in a regular octahedron in each medium cage. Dye adsorption studies revealed a rapid and selective adsorption of cationic dyes and the adsorbed dyes can be released in saturated NaCl aqueous solution.
