Figure 4
Formation of chains of molecules 3a parallel to the a axis, showing the short contacts between O1 and the triazine ring of a neighbouring molecule (thick dashed bonds). The view direction is approximately parallel to the b axis, and the a axis runs horizontally. Two such chains, running mutually antiparallel, are connected by the borderline contacts S1⋯C6 (thin dashed lines). Hydrogen atoms are omitted. |
