title: 1,5-Bis[1-(2,4-dihy-droxy-phen-yl)ethyl-idene]carbonohydrazide dimethyl-formamide disolvate.
abstract: In the title compound, C(17)H(18)N(4)O(5)·2C(3)H(7)NO, two solvent mol-ecules are linked to the main mol-ecule via N-H⋯O and O-H⋯O hydrogen bonds, forming a hydrogen-bonded trimer. Intra-molecular O-H⋯N hydrogen bonds influence the mol-ecular conformation of the main mol-ecule, and the two benzene rings form a dihedral angle of 10.55 (18)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds link hydrogen-bonded trimers into ribbons extending along the b axis.
