Figure 3
Quinol–pyrazine (1/1) (1) viewed perpendicular to the (001) planes. Colour scheme: C green, H grey, O red and N blue. A similar doubly bridging motif to the dioxane structure is observed (circled). The layers occupy the (002) planes, and alternate layers contain chains passing along the [110] and [1[\bar 1]0] directions (note that the source of the differences in Miller indices between the dioxane and this pyrazine co-crystals is that the former has published coordinates referred to P21/a, while the latter is in P21/c).
