Figure 6
(a) Quinol–pyridine (1/2) (4) structure viewed perpendicular to the (21) planes. The doubly bridging motif gives a R44(10) graph set (cf. pyrazine, circled). (b) Quinol–pyridine (1/2) (4) viewed down the a axis. Colour scheme: C green, H grey, O red and N blue. The π-stacking of pyridine molecules from neighbouring ribbons can clearly be seen. |
