The new copper(II) complex Cu(C13H9N3O2Br)2H2O (N-(2-hydroxy-5-bromo- benzoyl)-N-(picolinylidene)hydrazine is abbreviated as HL ) was obtained from the refluxing solution of Cu(CH3COO)2H2O and HL in the ethanol-N, N-dimethylformamide mix solvent. Crystal data: triclinic, space group P , a = 10.8620(3), b = 11.7453 (3), c = 12.4417(2) ? ?= 62.255(0), ?= 79.097(2), ?= 86.764(2)? V = 1378.52(6) ?, Z = 2, Mr = 719.835, Dc = 1.734 g/cm3, F(000) = 714, (MoK) = 3.739 mm-1, T = 293(2) K, final R = 0.0594 and wR = 0.1416 for 2943 observed reflections with I > 2.0(I). The structure of Cu(C13H9N3O2Br)2H2O has been determined by X-ray analysis and revealed that two L-1 ligands coordinate to the copper(Ⅱ) ion through two oxygen and two nitrogen atoms from the hydrazine groups and two pyridine nitrogen atoms to form an elongated and distorted square-bipyramidal environment for Cu(Ⅱ). The complex is also characterized by 1H NMR spectroscopies
