4,4'-{[1,2-Phenyl-enebis(methyl-ene)]bis-(-oxy)}di-benzoic acid di-methyl-formamide disolvate.

ABSTRACT: In the title solvate, C22H18O6·2C3H7NO, the complete dicarboxylic acid molecule is generated by a crystallographic twofold axis, which bisects the central benzene ring and one N,N-di-methyl-formamide solvent mol-ecule. The dihedral angle between the central and pendant benzene rings is 54.53?(5)° while that between the pendant rings is 45.44?(5)°. In the crystal, the acid molecules are linked to the solvent molecules via O-H?O and weak C-H?O hydrogen bonds. Further weak C-H?O inter-actions link adjacent acid mol-ecules into a three-dimensional network.
