title: N,N'-disalicyloylhydrazine.
abstract: The approximately planar mol-ecule of the title compound, C(14)H(12)N(2)O(4), is centrosymmetric and has an E configuration with respect to the N-N bond. This compound adopts the ketoamine form with C=O and C-N distances of 1.233 (3) and 1.331 (4) Å, respectively. Adjacent mol-ecules are assembled into a two-dimensional supra-molecular structure parallel to the (101) plane via inter-molecular O-H⋯O hydrogen bonds.
