Figure 6
The structure of polymorph II of the 1:1 SM–24DHBA co-crystal. Parallel zigzag tapes formed by imide–hydroxyphenyl heterodimers between SM and 24DHBA molecules extend into a sheet through acid–carbonyl, hydroxyl–carbonyl and C—H⋯O interactions. The para-hydroxyl conformation in 24DHBA is cis with respect to the carbonyl of the acid group. Dotted lines indicate hydrogen bonds.
