title: 1,5-Bis-[1-(2-hy-droxy-phen-yl)ethyl-idene]carbonohydrazide dimethyl-formamide monosolvate.
abstract: In the title compound, C(17)H(18)N(4)O(3)·C(3)H(7)NO, the main disubstituted urea and solvate mol-ecules are linked by pairs of N-H⋯O hydrogen bonds. In the main mol-ecules, the benzene rings form a dihedral angle of 15.59 (13)° a;nd two intra-molecular O-H⋯N hydrogen bonds influence the mol-ecular conformation. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the hydrogen-bonded pairs into chains along the b axis. The chains associate via C-H⋯π inter-actions.
