The copper complex [Cu(C23H27Br2N4O2) (H2O)(NO3)]2 was synthesized and characterized by X-ray diffraction. The complex crystallizes in the triclinic system with space group P-1, lattice parameters: a = 13.2293(18) (A° ), b = 14.184(20) (A ° ), c = 16.522(23) (A° ), a = 91.923(2), b = 111.777(2), c = 111.259(2), V = 2632.0(6) A ° 3, Z = 4, Dc = 0.88 Mg m-3. In the title compound [Cu(C23H27Br2N4O2)(H2O)(NO3)]2, the coordination polyhedron of the Cu atom is a square-planar environment. The structure consists of mononuclear units in which the copper(II) ions are linked in the plane by N,N0 iminato and O,O0 phenoxo atoms. In addition the crystal lattice contains one water molecule per unit.
