Figure 4
A perspective c-axis plot of part of the crystal packing of room-temperature polymorph (2rt). The discrete unique molecule in the centre of the plot (colored red in the electronic version of the paper) is surrounded by eight hydrogen-bonding acceptor molecules, although hydrogen bonding does not form small cyclic motifs as in polymorph (1).
