| Abstract: | Six zinc(II) complexes, Zn(HL)Br2 (1), Zn(HL)Cl2 (2), ZnL(OAc) (3), ZnLN3 (4), ZnL2 (5) and ZnL2 · H2O (6), have been synthesized and characterized by different physicochemical techniques. Complex 1 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−). |
