Abstract

A hydrogen-bonded metallocyanide-based (AZE)₂(H₃O)[Co(CN)₆] framework was obtained by introducing a hydronium cation to the A₂B(1)B(2)CN₆-type structure. Simple K⁺/H₃O⁺ substitution exchange the three-dimensional structure of the double-perovskite into two-dimensional layers containing open inorganic cages with a strongly discontinuous improper ferroelastic phase transition.
