Two novel trinuclear oxamato-bridged thiosemicarbazone complexes, [Cu(obte)]2Cd(DMF)2 (2) and [Cu(obte)]2Mn(DMF)2 (3) (H2obte = N-(2-benzaldehyde) oxamic acid ethyl ester thiosemicarbazone (1); DMF = dimethylformamide), have been synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TGA) and single-crystal X-ray diffraction. Complexes 2 and 3 are isostructural, displaying a trinuclear structure. The luminescence properties of complexes 2 and 3 were investigated in the solid state at room temperature. The ligand 1 and its complex 2 have been evaluated for their antitumor activities against K562 cells.
