Synthesis, characterization and crystal structure of cis-bis[4-fluoro-N-(diethylcarbamothioyl)benzamido-κ2O,S]platinum(II)

Abstract

cis-Bis[4-fluoro-N-(diethylcarbamothioyl)benzamido-κ²O,S]platinum(II), cis-[Pt(L-O,S)₂], was synthesized and characterized by elemental analyses, FT-IR and NMR techniques. The obtained metal complex was also characterized by a single crystal X-ray diffraction study. Molecule formula of the title compound is C₂₄H₂₈F₂N₄O₂PtS₂: tetragonal, space group I4₁/a, a = 19.7530(4) Å, b = 19.7530(4) Å, c = 13.7137(3) Å, V = 5350.83(19) ų, Z = 8, D_calc = 1.742 g/mm³, 22890 reflections measured (3.62 ≤ 2Θ ≤ 52.72), 2733 (R_int = 0.0272), which were used in all calculations. A square-planar coordination geometry is formed around the Pt atom by two S atoms and two O atoms of the N-(diethylcarbamothioyl)-4-fluorobenzamide ligand which are a cis configuration.
