3,3′-(3,6-Dihydroxy- p-phenylene)bis(4,7-dihydroxy-2 H-chromen-2-one) dimethylformamide trisolvate.

The two chromen-3-yl substituents at the 2- and 3-positions of the 1,4-dihydroxy­benzene in the title dimethyl­formamide (DMF) tris­olvate, C24H14O10·3C3H7NO, are aligned at 67.1 (1) and 69.8 (1)° with respect to the central aromatic ring. The 1-hydr­oxy group serves as a hydrogen-bond donor to a DMF whereas the substituent at the 3-position functions as a hydrogen-bond donor to two DMF mol­ecules. The other three hydr­oxy groups inter­act with donor sites of adjacent mol­ecules, generating a three-dimensional network architecture. [ABSTRACT FROM AUTHOR]
