Figure 2
A view along the a axis of one layer of the title compound, showing the (4,12)-network formed from linking octahedral AlO₄N₂ and tetrahedral HPO₄ and H₂PO₄ units. The four- and 12-membered rings (4 and 12 MR) referred to in the Comment are labelled, together with atoms O1, O2 and O7. The C atoms of 2,2′-bipyridine and all H atoms have been omitted. Short O⋯O contacts, indicative of intralayer hydrogen bonds, occur between the terminal O6 group and the O2—H, O3—H and O7—H groups. Key: Al black spheres, P grey spheres, O white spheres and N small grey spheres. [Symmetry codes: (i) $[x, -y+{1\over2}, z+{1\over2}]$ ; (ii) -x+1, $[y+{1\over2}]$ , $[-z+{1\over2}]$ ; (iii) -x+1, -y+1, -z+1; (iv) x, y+1, z.]
