2-Bromo-4-chloro-6-[(2,6-diisopropyl-phen-yl)imino-meth-yl]phenol.

ABSTRACT: There are two molecules in the asymmetric unit of the title compound, C(19)H(21)BrClNO, with dihedral angles between the aromatic rings of 70.0 (2) and 81.9 (3)°. The crystal structure is stabilized by inter-molecular C-H⋯π and C-Br⋯π inter-actions. In additional, the stacked mol-ecules exhibit intra-molecular O-H⋯N hydrogen bonds.
