| Summary: | Synthesis and spectroscopic characterization of gallium(Ill) complexes with chalcone and
Schiff base are reported in this thesis. Tautomerization was happening in chalcone before
coordinated with gallium(Ill) bromide. For Schiff base compounds, which OH group
located in ortho- or puru- substitution, a intramolecular hydrogen bond present between
hydrogen atom from phenolic group with nitrogen atom from C:= N group. Reactions of
chalcone as well as Schiff base with gallium(Ill) bromide gave a new respective
coordination mode of Ga-O bonds. The ligands appear to act as monodentate species in
Ga(III) complexes, making gallium atom four-coordinated in tetrahedron structure. The
ratio between Ga : ligand is 1: 1 for all the Ga(III) complexes in this research. |
