“…The d-d transitions are related to 4 T1g→ 4 T1g(p) and 4 T1g→ 4 A2g in Co(II) and 3 A2g→ 3 Eg in Ni(II) complexes. According to these transition, for Cu(II) and Ni(II) square-planner geometry are proposed, but octahedral geometry is suggested for Co(II) complex [13][14][15]. The mass spectra of the complexes are in good agreement with the proposed structures.…”

A novel series of metal complexes of 2-(thiazol-2-ylimino) thiazolidin-4-one ligand were prepared; the corresponding ligand was synthesized from reaction 2-Chloro-N-(thiazol-2-yl) acetamide with ammonium thiocyanate. The complexes are characterized by FTIR, UV-Vis, molar conductance and mass spectroscopy. The low molar conductance values indicate that the complexes are non-electrolytes.Spectroscopic studies confirmed that the ligand bonded to the metals through the sulphur atoms. Coordination number of copper and nickel complexes is four with square planar geometry, while the cobalt complex has octahedral geometry.In vitro antibacterial activity of ligand and its metal complexes was evaluated using well diffusion method and compared to the standard drug (tetracycline). The antibacterial activitywas examined against Escherichia coli, and pseudomonas aeruginosa, as gram negative bacteria and Staphylococcus aureus as gram positive bacteria. It was found that Nickel complex has the highest antibacterial activity among the synthesized compounds with Zone inhibition diameter in the range 25-29 mm.

Synthesis and characterization of new Pt(II) complexes of cyclohexanespiro-5-(2-thiohydantoin) (L1) and cycloheptanespiro-5-(2-thiohydantoin) (L2) are discussed. The new complexes are studied by elemental analysis, IR and 1 H NMR spectroscopy. The free ligands are investigated by UV-Vis, IR, 1 H NMR, 13 C NMR and Raman spectroscopy. The ground-state equilibrium geometries of the ligands L1 and L2 and their complexes with Pt(II) are optimized at the BLYP/CEP-31G theoretical level.

“…Recently, we studied the complexation properties of (9'-fluorene)spiro-5-hydantoin and its 2-thio derivative with Pt(II) 29 and Cu(II) 30 , as well as we reported the synthesis and structural characterization of new Cu(II) and Ni(II) complexes of (9'-fluorene)-spiro-5dithiohydantoin. 31 The two Pt(II) complexes show significant effects on cancer cell growth compared to their ligands. We also studied the complexation properties of cyclohexanespiro-5-(2,4dithiohydantoin) with Cu(II) and Ni(II).…”

The present work presents a synthesis, characterization and antimicrobial activitiy of new Pt(IV) and Ru(III) complexes of (9'-fluorene)-spiro-5-hydantoin (HL1) and (9'-fluorene)spiro-5-(2-thiohydantoin) (HL2). The complexes were investigated by elemental analysis, UV-Vis and IR spectroscopy. The free ligands were studied by UV-Vis, IR, 1 H NMR, 13 C NMR and Raman spectroscopy. The antimicrobial tests of HL1 showed week bacteriostatic effect against Staphylococcus aureus ATCC 6538. The results for [Pt(L1) 2 (H 2 O) 2 (OH-) 2 ] complex showed a good antimicrobial activity against Esсherichia coli ATCC 8739, Bacillus licheniformis ATCC 6633, S. aureus and the absence of such effect on the yeasts. The HL2 and its [Pt(L2) 2 (H 2 O) 2 (OH-) 2 ] and [Ru(L2) 3 (H 2 O) 3 ] complexes do not possess antimicrobial activity against the tested bacteria and yeasts.
