Synthesis, Characterization, Crystal Structure and Thermal Behavior of N'-(4-chlorobenzoyl)-N,N-di-n-butylthiourea and Its Nickel Complex

We report the synthesis, structural characterization and thermal behavior of N'-(4-chlorobenzoyl)-N,N-di-n-butylthiourea (HL) and its nickel complex (NiL2). Some physical properties of the prepared compounds were investigated using elemental analyses, IR, 1H-NMR, and magnetic susceptibility. The molecular structures of HL and NiL2 were determined by single crystal X-ray diffraction. HL is a monoclinic, space group P21/c with a = 10.7457(5) Å, b = 15.5909(8) Å, c = 10.4536(5) Å, b = 104.398(1)°, and V = 1696.34(14) Å3 with Z = 4 for dcalc = 1.280 g/cm3. NiL2 is a triclinic, space group P-1 with a = 8.561(3) Å, b = 16.643(6) Å, c = 25.723(9) Å, a = 77.448(6)°, b = 84.077(7)o, g = 88.684(6)°, and V = 3558(2) Å3 with Z = 4 for Dcalc = 1.326 g/cm3. The ligands coordinate to the metal atom in a bidentate manner, yielding an essentially neutral complex of the type ML2. Thermal decomposition of related compounds was investigated by TG and DTA. The pyrolytic end product was identified by X-ray powder diffraction.
