Water difference : Using H 2 O as the reaction medium in a conventional hydrothermal synthesis gives two nonporous materials with dense dia frameworks, dia(Zn) and dia(Co), from 2‐methylimidazole and M(OAc) 2 (M=Zn, Co; see structures, left). However, separation of the H 2 O and a solid mixture of the same starting materials in a steam‐assisted conversion gives open‐framework porous materials, ZIF‐8 and ZIF‐67 (right).
