Figure 5
A stereoview of part of the crystal structure of compound (IV)

, showing the formation of a chain of centrosymmetric R₂²(8) and R₂²(16) rings. The original atomic coordinates (Wang et al., 2006

) have been employed. For the sake of clarity, the dimethylformamide component has been omitted, and H atoms not involved in the motifs shown have been omitted.
