【 摘 要 】

Schiff base ligands 2-bromo-4-chloro-6-[(2-piperidin-1-ylethylimino)methyl]phenol(BCP) and 2,4-dibromo-6-[(2-morpholin-4-ylethylimino)methyl]phenol(DBP) and their nickel(II) and copper(II) complexes [Ni(BCP)2(CH3OH)2]2NO3(1) and [Cu(DBP)2] (2), have been preparedand characterized by elemental analyses, IR, and single crystal X-ray crystallographicdetermination. The crystal of (1) is orthorhombic: space group Pbcn,a = 23.894(1), b= 8.244(2), c = 19.900(2) Å, V =3919.9(10) Å3, Z = 4. The crystalof (2) is monoclinic: space group P21/c, a= 7.072(2), b = 15.426(3), c = 14.214(3) Å,β= 96.718(2)°, V = 1540.0(7) Å3,Z = 2. The Schiff bases coordinate to the metal atoms through the phenolateO and imine N atoms. The Ni atom in (1) is in an octahedral coordination,and the Cu atom in (2) is in a square planar coordination.
