supramolecular structure of 2, as shown in Fig. 3b.
In 1 and 2, the dihedral angles between ring B and C are
45.4 (66) ° and 40.8 (46) °, respectively, showing that rings
B and C are severely twisted across the C–C single bond,
which provide the potentiality of the formation of a helix
structure. X-ray single crystal diffraction studies show that
O–HꢀꢀꢀO hydrogen-bonds exit between the carboxylate
group of ring C and carbonyl oxygen atom of ring B, which
help to link the fla molecules into a helix chain structure in
1 and 2. However, in 1 helix chains are further joined by
DMF molecules; and in 2 helix chains are further linked via
hydrogen-bonds between fla molecules; which result in
different packing of modifications 1 and 2.

Flavone-6,20-dicarboxylic acid (fla) was found to exhibit
two different conformations. One crystallizes from
N,N-dimethylformamide in orthorhombic group Pbca and
the other crystallizes from n-propanol in monoclinic group
P2(1)/c without any solvent molecules. Rich hydrogen-
bonds and aromatic-aromatic interactions link fla mole-
cules to two different supramolecular structures.
