Figure 2
Part of the structure of (I[link]), showing the connectivity of the di­hydrogen­phosphate units (shaded tetrahedra) into [001] chains via pairs of O—H⋯O hydrogen bonds (H⋯O portion shaded; shown as green in the online version). Each organic moiety is pendant to a particular H2PO4− group. Adjacent chains interact via weak π–π stacking interactions (lines linking pyridine-ring centroids; shown as orange online). Sphere radii are arbitrary. (C, N, O and H atoms are shown as blue, green, red and grey spheres, respectively, in the online version.)
