摘要

In this study, four new complexes of p -coumaric acid/coumarin mixed ligand with Co(II), Ni(II), Cu(II) and Zn(II) transition metal were synthesized and the structures of these new complexes were determined. The Cu(II) complex is except the all of them have hydrate water. While, the acidic ligand is coumaric acid was coordinated to metal cation as bidentate in Cu(II) complex, it was bonded monodentate in the other complexes. The thermal decomposition starts dehydration in Co(II), Ni(II) and Zn(II) complexes, but it starts with fragmentation of organic ligands at 145°C in Cu(II) complex. In addition, structural characterization studies completed of molecules of biological activation studies were performed in cell culture medium. Molecular formulas of the obtained complex are as follows: ( I ) [Co(C 9 H 7 O 3 ) 2 (C 9 H 6 O 2 ) 2 (H 2 O) 2 ] . 4H 2 O ( II )[Ni(C 9 H 7 O 3 ) 2 (C 9 H 6 O 2 ) 2 (H 2 O) 2 ] . 6H 2 O ( III ) [Cu(C 9 H 7 O 3 ) 2 (C 9 H 6 O 2 ) 2 ] ( IV ) [Zn(C 9 H 7 O 3 ) 2 (C 9 H 6 O 2 ) 2 (H 2 O) 2 ] . 3H 2 O The rates of metal: p -coumaric acid: coumarin in complexes were found as 1:2:2. The complex IV is diamagnetic, and the other complexes are paramagnetic. According to BM data and result of electronic spectra, the geometry for all of the complexes has thought to be octahedral coordination around the metal ions.
