摘要：

Six zinc(II) complexes, Zn(HL)Br-2 (1), Zn(HL)Cl-2 (2). ZnL(OAc) (3), ZnLN3 (4), ZnL2 (5) and ZnL2 center dot H2O (6). have been synthesized and characterized by different physicochemical techniques. Complex I is five coordinated and has a distorted square pyramidal geometry. Complexes 5 and 6 are six coordinated and have distorted octahedral geometries. In complexes 1 and 2, the ligand moieties are coordinated in the neutral form (HL). and in the other complexes they are monoanionic (L-). (C) 2008 Elsevier Ltd. All rights reserved.
