Experimental

R factor = 0.034; wR factor = 0.082; data-to-parameter ratio = 20.9. In the title compound, [Cu(C11H11BrNO)2], the Cu II atom is in a distorted square-planar geometry, with the two bidentate ketimine ligands positioned in a trans geometry. Two inter-molecular C—H O hydrogen bond interactions are present which link the molecules in a zigzag manner along the a axis. The molecules pack in layers along the diagonal of the bc plane.
