“…28 The IR spectrum of complex 3 had additional non-ligand bands at 2072, 777 and 493 cm -1 , assignable to ν(C-N), ν(C-S) and δ(NCS) of thiocyanate. 29 The presence of these bands revealed the N-coordinated nature of the thiocyanate ion. 29 The spectrum of complex 2 exhibited additional non-ligand bands at 1248, 1177 and 1085 cm -1 , and the values showed the bridging bidentate coordination of the sulphate group.…”

Thorium(IV) complexes with the Schiff base furan-2-carboxaldehyde4-phenyl-3-thiosemicarbazone (L) were synthesised and characterized. The composition and structure of the metal complexes were proposed based on elemental analysis, molar conductivity measurements, FTIR and 1 H-NMR spectroscopy. The Schiff base behaves as a neutral bidentate ligand coordinating through the azomethine N and the thioketo S atoms. From various studies, complexes were ascertained the general formula [ThL 2 X 4 ] and [ThL 2 Y 2 ], where X represents NO 3 -, NCS -, CH 3 COO -, CH 3 CHOHCOO -, ClO 4 -and Y SO 4 2-and C 2 O 4 2-. The thermal behaviour of the nitrato and oxalato complexes was studied and kinetic and thermodynamic parameters were calculated using the Coats-Redfern Equation. The ligand and a representative complex [ThL 2 (NO 3 ) 4 ] were screened in vitro for their antitumour activity against the human cervical cancer cell line (HeLa).
