N′-(1E)-3-Bromo-5-chloro-2-hy­droxy­benzyl­idene-4-tert-butyl­benzo­hydrazide ethanol monosolvate

摘要

In the title compound, C18H18BrClN2O2·C2H6O, the hy­droxy group forms an intra­molecular O—H⋯N hydrogen bond, which influences the conformation of the Shiff base mol­ecule, where the two aromatic rings form a dihedral angle of 21.67 (8)°. Inter­molecular N—H⋯O and O—H⋯O hydrogen bonds link two Shiff base mol­ecules and two solvent mol­ecules into a centrosymmetric heterotetra­mer. Weak inter­molecular C—H⋯O inter­actions link further tetra­mers related by translation along the a axis into chains.
