title: 6,6'-Dieth-oxy-2,2'-[hexane-1,6-diylbis(nitrilo-methanylyl-idene)]diphenol.
abstract: The title compound, C(24)H(32)N(2)O(4), is a polydentate Schiff base and reveals strong intra-molecular O-H⋯N hydrogen bonding between the hy-droxy O atom and the imino N atom, with an O⋯N distance of 2.570 (3) Å. In the crystal, a centre of inversion is located at the mid-point of the compound. The diimino-hexyl-ene chain is almost ideally in the anti conformation, with an average dihedral angle of 179.0°.
