A framework of AlO 6 octahedra is present in the microporous aluminoborate HAl 3 B 6 O 12 (OH) 4 (PKU‐1; see picture), which was synthesized from AlCl 3 in a boric acid flux. The octahedra share two or three edges with neighboring octahedra to form a framework with 18‐ring tunnels along [001] and 10‐ring tunnels along {100}. The borate groups share vertices with the octahedra, compensating the negative charge of the octahedral framework and almost completely blocking the 10‐ring channels.
