Two new Cu(II) complexes have been synthesized with two different bidentate N_2O_2 donor Schiff base ligands HL_1 (2-((E)-(4-chlorophenylimino)methyl)-6-bromo-4-chlorophenol) and HL_2 (2-((E)-(2-chlorophenylimino)methyl)-6-bromo-4-chlorophenol), respectively. Both complexes 1 and 2 have been characterized by elemental analysis and single-crystal X-ray diffraction studies. Structural studies reveal that in both complexes the metal centers are four-coordinated with N_2O_2 donor set of Schiff base ligands. Complex 1 belongs to the tetragonal system, space group P4(3)2(1)2 with a = 10.2379(2), b = 10.2379(2), c = 24.9623(90) , V = 2616.41(12) ~3, Z = 4, D_c = 1.908 g/cm~3, μ(MoKα) = 4.3327 mm~(-1), F(000) = 1468, S = 0.999, the final R = 0.0345 and wR = 0.0835 for 3506 unique reflections (R_(int) = 0.0428) with 3249 observed ones (I > 2σ(I)). Complex 2 is of monoclinic system, space group P21/c with a = 11.064(3), b = 9.437(2), c = 13.277(4), β = 108.997(3)°, V = 1310.8(6) ~3 , Z = 2, D_c = 1.904 g/cm~3, μ(MoKα) = 4.319 mm~(-1), F(000) = 734, S = 0.997, the final R = 0.0282 and wR = 0.0619 for 3491 unique reflections (R_(int) = 0.0428) with 2777 observed ones (I > 2σ(I)). The units of the complex are linked via weak interactions, such as C-H…Br hydrogen bonds together with Cl…Cl and Cu…Cl interactions, leading to the formation of one-dimensional chain and two-dimensional network and stabilizing the crystal structure.
