| Abstract: | A new semicarbazone (HL) based on di-2-pyridyl ketone and its three cadmium(II) complexes [CdL(CH3COO)]2 · 2CH3OH (1), Cd(HL)Br2 (2) and [Cd2L2N3]2 · H2O (3) were synthesized and characterized by different physicochemical techniques. The complex, [CdL(CH3COO)]2 · 2CH3OH (1) is having a dimeric structure. In complexes 1 and 3, the ligand moieties are coordinated as monoanionic (L−) forms and in complex 2, the ligand is coordinated as neutral (HL) one. The coordination geometry around cadmium(II) in 1 is distorted octahedral, as obtained by X-ray diffraction studies. |
