摘要：

The new copper(II) complex Cu(C13H9N3O2Br)(2)(H2O)-H-. (N-(2-hydroxy-5-bromobenzoyl)-N-(picolinylidene)hydrazine is abbreviated as HL) was obtained from the refluxing solution of Cu(CH3COO)(2)H2O and HL in the ethanol-N, N-dimethylformamide mix solvent. Crystal data: triclinic, space group P (1) over bar, a = 10.8620(3), b = 11.7453 (3), c = 12.4417(2) Angstrom, alpha = 62.255(0), beta = 79.097(2), gamma = 86.764(2)degrees, V = 1378.52(6) Angstrom(3), Z = 2, M-r = 719.835, D-c = 1.734 g/cm(3), F(000) = 714, mu (MoKalpha) = 3.739 mm(-1), T = 293(2) K, final R = 0.0594 and wR = 0.1416 for 2943 observed reflections with I > 2.0sigma(I). The structure of Cu(C13H9N3O2Br)(2)(H2O)-H-. 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 H-1 NMR spectroscopies.
