a) Space‐fill and b) capped sticks representation of the top view of BN‐MOF‐2 crystal structure showing the hexagonal networks and the rhombic channels resulting from the relative 60° rotation of borazine cores in each layer; c) space‐fill and d) capped sticks representation of the side view of BN‐MOF‐2 showing the layered structure; e) zoomed inset of the borazine cores highlighting the interlayer distance; colour code: C grey or coloured in orange and green for the two different networks; pink: B, blue: N, red: O, black or dark blue tetrahedron: Zn. H atoms were omitted for clarity.
