ABSTRACT: In the title mononuclear Schiff base copper(II) complex, [Cu(C(12)H(16)BrN(2)O)(NCS)], the Cu(II) ion is coordinated by two N atoms and one O atom from a Schiff base ligand, and by one N atom from a thio-cyanate anion, giving a square-planar geometry. There are long-range inter-actions between the Cu atom and S [3.151 (5) Å] and Br [3.929 (5) Å] atoms above and below the square plane.
