Abstract

The asymmetric unit of the title compound, C(16)H(24)Br(2)N(2)O(2), contains two independent mol-ecules, each which has two intra-molecular N-H⋯O hydrogen bonds linking the amine N atoms to the enolic O atoms of the same acacH-imine unit. In the crystal, the mol-ecules are lined up by inter-molecular weak C-H⋯O hydrogen bonds, forming two vertical each other two-dimensional chains along the a axis and b axis of the unit cell, respectively.
